What's the most important factor to consider when choosing an airline, in your opinion? Share one factor and explain why it's a priority for you.

I will always select a non-budget airline where possible. Spacious seats, more room, better food etc. For example, KLM do good food, great seats, a pleasurable experience. Cost matters as with most things but it is not the most important factor. Flying is an experience as much as the rest of the holiday.
