Today: 10 tips for sustainable air travel

Yesterday was Earth Day, a moment to reflect about the environmental impact of our travels, especially when it comes to booking a flight. Air travel is widely regarded as the least environmentally-friendly way to get around the world, despite its incredible efficiency in covering a wide distance in a short time. There’s no getting around it: aircraft engines burn fuel, which release Carbon Dioxide (CO₂), so the more we fly, the more CO₂ goes into the atmosphere. Aviation is now responsible for 2% of all global carbon emissions and that will only increase in the future as the number of air passengers is expected to double in 20 years. The good news is that earth-conscious travelers can make a difference by adjusting their air travel preferences and habits. Here are 10 tips to fly as sustainable as possible.

• Make use of alternative, more environmentally friendly forms of transport such as rail or motor coach for short-haul travel. Aircraft use more fuel during takeoff and landing than cruising, so for shorter flights, this accounts for a larger proportion of the journey. This is worth considering when traveling shorter distances you could reach by other means. For example, going by high-speed train from Paris to Brussels is not only greener, it also goes faster than traveling by plane.​

• Consider carbon offsetting for lowering your impact as an air traveler. Carbon offsetting is a way to “neutralize” your proportion of an aircraft’s carbon emissions on a particular journey by investing in carbon reduction projects. Over 30 airlines have introduced an offset program either integrated into their web-sales engines or to a third party offset provider. For example, when you fly with KLM, you can choose the airline’s CO2ZERO service when you book a flight and contribute to the ‘CO2OL Tropical Mix’ reforestation initiative in Panama where so far at least 7,5 million trees have been planted.

• Consider flying Economy Class as stretching out in luxury in Business & First Class comes at a high cost for the environment. That’s because passengers in a plane’s premium cabin use more space and are thus accountable for a greater share of the aircraft’s fuel consumption. To give you an idea, according to a study by the United Kingdom’s Department for Business Energy & Industrial Strategy, carbon emissions per passenger per mile traveled are about three times higher for Business Class and four times higher for First Class when compared to Economy Class.

• Pack lightly. Every pound of a weight on a plane increases the amount of fuel that it burns, so the heavier your luggage, the higher your carbon footprint. Reducing your luggage by 15 kg (33 lbs) could save between 100 and 200 kg (220 to 440 lbs) of CO2 emissions on a return flight from London to Lisbon. According to Delta Airlines, “If customers pack lighter, making simple changes like leaving that extra pair of shoes at home the annual environmental impact from reduced fuel consumption is the equivalent to removing 10,500 cars from the road for an entire year.”

• Choose daytime flights as this is believed to be a more eco-friendly and sustainable mean of air travel. Studies show that airplanes can contribute to global warming because their contrails can trap heat radiating up from earth that would otherwise escape our planet. This is especially the case during the nighttime because during the day, the contrails partially offset the heat trap effect by radiating light from the sun away from the earth.

• Take a non-stop flight. Since take-off and landing burns the most fuel (up to 50% of a flight’s emissions), flying point-to-point without stopovers is the best way to reduce your carbon emissions when flying. So with the dawn of ultra long-haul flights such as Qantas’ London to Perth route and its anticipated “Project Sunrise” connecting Sydney with New York, London and Paris (due in 2023), we may expect to travel halfway around the world with a much lower carbon footprint and in a more sustainable way.

• Opt for one of the vegan or vegetarian in flight meal options as a meat-based meal has a carbon footprint 50% greater than a plant-based meal (animal agriculture produces around a fifth of all man-made greenhouse gas emission). Airlines serve an estimated one billion inflight meals every year, so choosing a plant-based options can help reduce the industry’s carbon emissions. Fortunately, many airlines are currently expanding their vegan and vegetarian options in light of consumer demand for more sustainable air travel. For example, Qatar Airways’ menus include vegan dishes like spiralised courgettes with arrabbiata sauce, Asian barbecue tofu with noodles, cauliflower couscous with Kalamata olive bruschetta; and chickpea flour omelette.

• Take a low-waste flight. Prior to the corona pandemic, airline passengers generated over 7.3 million tons of cabin waste. The key culprit here is plastic, including plastic-wrapped blankets, disposable toothbrushes, single-use cutlery and non-compostable coffee cups. A plastic straw, for example, can take up to 200 years to break down in the environment – also resulting in wildlife ingesting it and causing harm. But change is coming. In January 2019, Portuguese airline Hi Fly completed the world’s first plastic-free flight (from Poprtugal to Brazil). Other airlines including Emirates, Qantas and Air New Zealand quickly followed suit and have introduced plans to significantly reduce the amount of waste they send to landfill.

• Pick airlines with modern, fuel-efficient planes such as the Airbus A350 and Boeing B787, the first large commercial aircraft to be constructed extensively from lightweight composites (which accounts for 53% and 50% of the A350 and B787 fuselage respectively). The main advantage of composites is that these components are lighter than similar parts made of aluminium, which means a lighter aircraft and thus less fuel burn. In addition, carbon-fiber reinforced polymers have increased resistance to corrosion and don’t suffer from fatigue to the same extent as aluminum, which translates into more durable airframes and lower maintenance costs.

• Fly an environmentally conscious airline that is supportive of sustainable air travel by minimizing its carbon emissions. Fortunately, there are websites such as alternativeairlines.com that help you find the greenest airline. For example, Etihad Airways and Boeing have an eco-partnership, in which a specially-themed Boeing 787 Dreamliner is used to test products, procedures and initiatives designed to reduce aircraft carbon emissions.  The ‘Etihad Greenliner’ is used to assess environmental sustainability initiatives (e.g. changed operating practices to weight-saving initiatives) while the aircraft operates scheduled services across the airline’s network.

Today (April 17, 2020): What air travel might look like post the COVID-19 lockdown?

How soon are we going to be allowed to travel again freely after the coronavirus pandemic is over, and what will air travel look like? Those are the questions that every traveler (including myself) is asking in every corner of the globe. The good news is that eventually, we will get past this horrible COVID-19 pandemic, whether by means of a vaccine, therapeutic regimens, and/or herd immunity. However, the realities of a post-COVID-19 world will pose new challenges to the travel industry and airlines in particular, since airports and aircraft are also all about density, which is the antithesis of social distancing. When air travel ramps up again, it’s likely passengers and cabin crew will be nervous about being in close proximity to others in a contained space. With that in mind, airlines and health authorities across the world are considering what air travel might look like in the future. Here’s a look at eight measures travelers are likely to see when flying, and which are needed not only to contain the future spread of the virus, but also to regain passenger trust.

What do you think travel will look like post COVID-19? Leave a comment.

1. SOCIAL DISTANCING DURING THE CHECK-IN PROCESS

Airline’s check-in and boarding formalities will have to be adapted with social distancing in mind. Protective barriers will be installed at each check-in desk to provide additional safety measures to passengers and airline employees during any interaction. Gloves, masks and hand sanitizers will be made mandatory for all employees at the airport. A 1,5 m (5 ft) distance between passengers at airports from the entry gate to boarding gates will be required to maintain.

2. ONSITE RAPID TESTING FOR COVID-19 (BEFORE CHECK-IN)

It is likely that airlines will perform COVID-19 testing on passengers before they check-in. Emirates has already begun conducting on-site rapid COVID-19: passengers on a recent flight to Tunisia were all tested for COVID-19 before departing from Dubai (watch the clip below). The quick blood test was conducted by the Dubai Health Authority and results were available within 10 minutes. This test was conveniently done at the check-in area of Dubai International Airport. Adel Al Redha, Emirates Chief Operating Officer said: “We are working on plans to scale up testing capabilities in the future and extend it to other flights, this will enable us to conduct on-site tests and provide immediate confirmation for Emirates passengers travelling to countries that require COVID-19 test certificates. The health of staff and passengers at the airport remain of paramount importance.”

Whether airport COVID-19 blood tests will become the new norm for all airlines remains to be seen: while they are accurate and simple, they remain time-consuming and expensive. If they do, I am sure that airlines will add a new health screening tax to the price of a ticket.

3. HEALTH SCREENING (BEFORE CHECK-IN)

During the COVID-19 pandemic, we have seen authorities across the globe checking the temperature of passengers as they travel and transit through airports. It’s an easy test to detect early fever in a coronavirus patient and could prevent infected passengers from accessing boarding (and infecting others). However, health screening may become more sophisticated in the near future, and some airlines are already taking steps to take it to the next level.

Etihad Airways has partnered with Australian company Elenium Automation to trial new technology which allows self-service devices at airports to be used to help identify travelers with medical conditions, potentially including the early stages of COVID-19. Etihad is the first airline to trial the technology, which can monitor the temperature, heart rate and respiratory rate of any person using an airport touchpoint such as a check-in or information kiosk, a bag drop facility, a security point or immigration gate. The Elenium system will automatically suspend the self-service check-in or bag drop process if a passenger’s vital signs indicate potential symptoms of illness. It will then divert to a teleconference or alert qualified staff on site, who can make further assessments and manage travelers as appropriate. The technology is ‘hands free’, enabling touchless use of self-service devices through voice recognition, further minimizing the potential of any viral or bacterial transmission.

Jorg Oppermann, Vice President of Etihad Airways, said: “This technology is not designed or intended to diagnose medical conditions. It is an early warning indicator which will help to identify people with general symptoms, so that they can be further assessed by medical experts, potentially preventing the spread of some conditions to others preparing to board flights to multiple destinations. We are testing this technology because we believe it will not only help in the current COVID-19 outbreak, but also into the future, with assessing a passenger’s suitability to travel and thus minimizing disruptions. At Etihad we see this is another step towards ensuring that future viral outbreaks do not have the same devastating effect on the global aviation industry as is currently the case.”

Aaron Hornlimann, CEO and Co-Founder of Elenium Automation, said: “Elenium has lodged patents for both the automatic detection of illness symptoms at an aviation self-service touchpoint, and touchless self-service technology at an airport. Combined, this would ensure health screenings can become standard across airports, without putting staff in harm with manual processes. The system would screen every individual, including multiple people on the same booking. The technology can also be retrofitted into any airport kiosk or bag drop or installed as a desktop system at a passenger processing point such as an immigration desk. We believe the introduction of touchless self-service and automated health screening will encourage passengers to return to travel sooner.”

4. IMMUNITY CERTIFICATES

Several research groups around the globe (e.g. Germany, Italy, UK, and USA) have proposed testing people for antibodies to SARS-CoV-2, the virus that causes COVID-19, and giving “immunity certificates” or “Covid passports” to those who have these antibodies, which presumably make them resistant to reinfection. Those with an COVID-19 immunity certificate could stop sheltering in place, help the world revive, and be some of the first to travel again.

The big problem is that no one knows whether infection with COVID-19 confers immunity to reinfection and, if it does, how strong that immunity is and for how long it lasts. Not only is that information missing, but we cannot get it soon – it will take along time before we can know if antibodies last a year. In addition, there is a wide variety of antibody tests on the market, some with questionable quality. Some detect antibodies that do not exist (false positives), others miss antibodies that do exist (false negatives).

So, as long that there is no robust test and as long as we don’t know more about the immune protection following a COVID-19 infection, there’s little chance that immune certificates will be required before traveling. In fact, getting them wrong could do more harm than good. However, in the long term, once a vaccine is available, I do assume that a vaccination certificate might be mandatory to enter several countries. This will be similar to the International Certificate of Vaccination or Prophylaxis (ICVP), which proofs that you have had yellow fever vaccine; some countries require all travelers to show proof of yellow fever vaccination before they can enter the country.

5. AN ENHANCED BOARDING PROCESS

So far, airlines have always tried to segregate passengers for boarding, by making them board in groups. However, chances are that in the near future, we will have to board according to the row number, so that passengers enter the plane from the rear and are seated one row at a time (in order to mitigate the chance of passengers crossing paths). Some airlines have already taken the boarding process to the next level. For instance, earlier this year Delta Air Lines launched a virtual queuing feature on its Fly Delta app, which notifies passengers when their seat is boarding. Similarly, Gatwick Airport and EasyJet also recently trialed boarding by seat number to try to reduce queues and boarding times. Although this might not be completely viable for all passengers, it will probably become a standard policy once travel demand increases again after the COVID-19 pandemic.

6. WEARING A MASK ON BOARD

Your chances of contracting COVID-19 on a plane are very small. Most aircraft are equipped with state-of-the-art circulation systems, similar to those found in hospitals, which use a high-efficiency (HEPA) filter to circulate the air and removes up to 99.7% of airborne particles (including coronavirus). So the risk, if there is one, does not come from the supplied air. It comes from other people. From what we know, the transmission of coronavirus is generally limited to the distance you cough or sneeze – which is about 2 m (7 ft). If you do get this type of virus on a plane, it’s likely because of a person seated within two rows around you. And that’s the reason that some airlines (e.g. Emirates, Turkish Airlines) now require their passengers to wear a mask, while others have not implemented this measure yet.

The evidence on the effectiveness of wearing masks (on a plane or in general) is somewhat mixed. Some studies say that they protect those around the wearer more than the wearer themselves: if a person who has flu-like symptoms wears a mask, they’ll sneeze into the mask instead of into the air, and as such protect the people around them. Others have entirely dismissed the value of wearing one, and say it may even give a false feeling of security as the mask can potentially catch the virus (in a water droplet) in the fabric. Time will tell whether we will be required to wear a mask after COVID-19, although it probably won’t be mandatory until substantial evidence can prove their effectiveness. Also, with proper pre-departure health checks, the need to wear a mask will be sufficiently diminished.

7. CHANGING THE ONBOARD SERVICE

Most airlines have already adjusted their onboard service during the COVID-19 pandemic to further avoid onboard transmission of the virus, such as:

• Flight attendants are wearing gloves during food and beverage service and pick-up.
• Flight attendants hand all beverages directly to the customer, instead of allowing the customer to take their own from the tray.
• All tableware, dishes, cutlery, carts and glassware are washed and sanitized
• Crews may make use of gloves, masks, alcohol-based hand sanitizer, wipes, foaming hand soap, and disinfectant wipes.
• Magazines and other print reading material are no longer available.
• Cabin baggage is limited on flights: carry-on items that are still allowed in the cabin are limited to laptop, handbag, briefcase or baby items. All other items have to be checked in.

It is likely these measures will stay in place once the COVID-19 pandemic is over.

8. BLOCKING THE MIDDLE SEAT IN ECONOMY CLASS

Right now, several airlines (including major carriers like Lufthansa and United) have temporarily blocked of the middle seat in Economy Class and allow passengers to move seats after takeoff, in order to practice social distancing. But some airlines have already lauded the new policy and consider leaving airplane Economy Class middle seats empty once COVID-19 restrictions ease and travelers return to the skies. One of these airlines is EasyJet, which has one of Europe’s largest commercial aircraft fleets, said the measure would be temporary and would form part of a package of strategies for safeguarding travelers. “Based on our discussions with European Union Aviation Safety Agency and other agencies, it is likely there may be new ways of operating,” an EasyJet spokesperson said in a statement. “This could include leaving middle seats empty to create more space for passengers.” As aircraft would operate with a reduced number of seats, this policy would of course  dramatically increase air fares.

Today (December 19, 2014): tips for healthy air travel.

Everyone wants to arrive at his/her destination feeling relaxed and refreshed! Regardless of whether you need to rejuvenate for your holiday or be effective at achieving your goals on a business trip, these simple tips will help you enjoy your journey while flying longhaul:

• Drink plenty of water. Rehydrate with water of juices frequently. Drink tea and coffee in moderation.

• Skip alcohol. Alcohol will dehydrate and bloat you. It could also cause you to miss your flight as airlines are not allowed to board passengers appearing to be intoxicated.

• Travel lightly. Carry only the essential item that you will need during your flight.

• Wear glasses. Cabin air is drier that normal, therefore swap your contact lenses for glasses.

• Use skin moisturizer. Apply a good quality moisturizer to ensure your skin doesn’t dry out.

• Strengthen your immune system. Eat right and exercise the day before you fly. Think fresh fruit and vegetables, less sugar, and whole grains. A healthy lifestyle may prevent you from catching your neighbors cold!

• Keep moving. Excercise your lower legs and calf muscles. This encourages blood flow.

• Make yourself comfortable. Loosen clothing, remove jacket and avoid anything pressing against your body.

• Sleep. Get a good nights rest the night before you fly. If not, flying will make you extremely tired. Add the stress you’ll probably be feeling and you have a recipe for exhaustion.

• Outsmart gems. Anyplace people are cooped up eating, sneezing, and touching stuff, things get dirty. Washing your hands or using alcohol-based hand sanitizer is the number-one way to avoid getting sick,

• Eat light. The rise in air pressure and stress during a flight can slow digestion, leaving you feeling inflated.

• Consider flying Business or First Class. Wellness and more comfort is guaranteed in the premium cabins. This does not have to cost you a fortune when you read my for finding the cheapest flight ticket.

Enjoy the weekend and stay tuned for Monday when I reveal a new top 10 travel list.
