From packing a reusable water bottle and reef-friendly sunscreen to making an effort to use fewer plastics and eat local and fresh while abroad, there are plenty of ways travelers can cut their carbon footprint while away from home. But no matter how many carbon-neutral hotels you book or reusable cutlery you pack, the elephant in the room is that air travel is traditionally one of the least sustainable modes of transport.

You don’t have to forgo air travel entirely in order to be a more eco-minded traveler. There have been considerable developments in the commercial aviation industry that will only continue to advance. Whether it’s airlines taking pledges to become more sustainable, switching to more sustainable fuels, ordering electric jets or offering carbon offsets, it’s true that certain commercial airlines have started to claim a significant stake in making air travel less damaging to the environment.

That said, creating a sustainable aviation industry is perhaps the greatest challenge for the sector since the invention of the airplane, says former pilot and president of The Aviation Agency Bryan Del Monte. “Physics, economics and global demand for air travel present a problem that will require as much innovation to overcome as the invention of the airplane required in the first instance,” he explains.

According to Del Monte, for a true net-zero approach to air travel, planes will need to be redesigned, airports will need to be reimagined and how fuel is derived, delivered and utilized in engines will have to be reimagined.

“In some instances, there is a tendency to engage in greenwashing, but there is also widespread acceptance and genuine efforts in solving these problems,” he says. “While the challenges are daunting, it’s not beyond the industry’s grasp. If anyone can find the solutions we will need to make air travel both sustainable and a continued part of modern life, it’s the men and women who work in the aerospace and aviation industry.”

It can be difficult to sift through the airlines that are making an actual difference and those that are simply catering to eco-minded travelers looking to clear their conscience through airplane carbon offsetting schemes. We’ve put together a list of the airlines doing the best job in taking these steps to become more sustainable in the long run.

European airline EasyJet has detailed its commitment to an interim science-based climate target for 2035 with an end goal to hit net-zero carbon emissions by 2050. Since 2019, the low-cost carrier is also the first and only airline in Europe to offer free carbon offsetting for passengers while publicly acknowledging that offsetting is only an interim solution to a much greater commitment to sustainable air travel. Plus, the airline has a fleet of modern, fuel-efficient planes, including Airbus neo aircraft, which are 15% more fuel efficient than older planes, on average.

How to fly with EasyJet: EasyJet is a low-cost airline in Europe, serving nearly 200 destinations across Europe and Northern Africa. You can expect to pay little for your flights, but expect to pay for extras like seat selection and checked bags.

Virgin Atlantic continues to be a leader in sustainability efforts. The British commercial airline is on track to hit net zero by 2050, thanks to a combination of ambitious innovation and transparency that includes a decade-long partnership with LanzaTech to build the first Sustainable Aviation Fuel (SAF) plant in the United Kingdom. So far, Virgin has become the first to operate a commercial flight on waste-based fuel, and since 2019, Virgin offers a way for passengers to offset their flights. The airline has also committed to having ​​one of the youngest and cleanest twin-engine fleets, having retired its four-engine Boeing 747s and Airbus A340s and replacing them with more fuel-efficient Boeing 787s and Airbus A350s. Currently, the average Virgin Atlantic aircraft is just 7 years old.

How to fly with Virgin Atlantic: Virgin Atlantic flies to more than 35 destinations around the world, including 12 major cities in the US. The airline is 49% owned by Atlanta-based Delta Air Lines and has partnerships in place with the airline as well as the likes of Air France, Hawaiian Airlines and KLM. You can even redeem your Delta SkyMiles to fly with Virgin Atlantic — in fact, that’s one of our favorite ways to use Delta miles. You’ll just have to pay the taxes and fees on the ticket if you choose to redeem travel rewards for a free flight.

As of 2022, KLM blends a small percentage of SAF for every flight departing from Amsterdam. In fact, the airline increased its prices based on the length of the flight and if you’re flying in economy or business class, in order to pay for the cost of SAF. KLM also works on reforestation efforts in Panama, encouraging passengers to donate money to its efforts. By 2035, KLM plans to introduce new electric- and hydrogen-powered aircraft into its fleet, and by 2050, the airline has a goal to become net zero.

“[KLM has] been developing eco-friendly fuel options since 2009, and have even completed commercial flights with biofuel,” says Struan Baird, co-founder of Luxury Scotland Tours. “Moreover, they go so far as to try and convince flyers to avoid flying whenever possible.”

How to fly with KLM: KLM serves over 140 destinations around the world via its home airport of Amsterdam (AMS). The airline does fly to several destinations in the US, including New York (JFK), Los Angeles (LAX), Washington, D.C. (IAD) and Boston (BOS), among others. The airline is part of the SkyTeam alliance, which is the same group of which Delta Air Lines is a member. Because of the partnership, you can earn and redeem Delta SkyMiles on KLM flights as well as work your way toward earning Delta elite status.

Air Canada is leading the way in its home country with an ambitious Climate Action Plan that includes committing to net-zero emissions by 2050. Currently, the airline’s newer and more energy-efficient Airbus A220 and Boeing 737 MAX narrow-body fleets average 20% less fuel consumption per seat and 50% less nitrogen oxide than its older-generation aircraft. Air Canada continues to invest in SAF and the development of other low-carbon aviation fuels (LCAF), and the airline offers passengers the option to carbon offset their flights.

Meanwhile, on its planes, Air Canada is making some sustainable decisions too. Since 2019, the airline has removed 47.8 million single-use plastic items from its planes. Plus, those in-flight amenities that often find themselves in the trash can? Air Canada has donated more than 24,000 amenity kits since 2018 as well as nearly 20,000 duvets and mattress pads since 2017.

How to fly with Air Canada: Air Canada is Canada’s largest domestic airline and serves more than 200 destinations on six continents. The Star Alliance member’s frequent flyer program, Aeroplan, is one of the better options out there, allowing you to earn and redeem points at a favorable rate. Plus, the Aeroplan program has a relatively new credit card option now available in the United States.

In October 2021, United Arab Emirates-based Etihad Airways operated its most sustainable flight ever as part of its Etihad Greenliner sustainability program. The flight saw a 72% reduction in calculated emissions, thanks to several key initiatives the airline also plans to implement in future flights, including sustainable in-flight products, better coordination with airspace management for optimized flight routing and utilizing SAF. The airline is taking its sustainability so seriously that it’s painted one of its Boeing 787 aircraft green, dubbing it the “Greenliner.”

Etihad also boasts a first-of-its-kind Corporate Conscious Choice program that rewards members for sustainable choices. Plus, the airline is dedicated to informing passengers about making more sustainable choices, including the option to carbon offset their flight as well as carrying less baggage so the aircraft can use less fuel.
