Several other airlines offer one-stop flights, which will be more cost-effective but increase your carbon footprint drastically.

When booking your flight keep a few things in mind to be a contributor to more sustainable travel. Firstly, make sure you are on time to catch your flight. If the pilot is forced to catch up the time he will be burning weight of extra fuel per minute. Make sure you pack light. Reducing the weight of your bag reduces your carbon footprint by 5%. Pre-book your meal directly with the airline. This will allow the airline to prepare and store only the meals needed for the flight, without having excess options that result in food waste. You can also bring your own recycled water bottle and ask for it to be refilled to avoid buying pre-bottled water on board.
