Looking for another reason to book a direct flight? Besides saving time and the hassle of connections, direct flights emit less CO2. Connecting flights don’t follow the shortest route, and they also burn up lots of fuel in the extra takeoffs and landings. Just one layover on a 2000-mile (4.5 hour) flight increases emissions by 10% or more — and that’s assuming the stop is directly on route!

If you can’t avoid flying, try to fly direct.
