1. The food is often overcooked
Airline food catering companies usually supply airlines with a variety of frozen food, but there are exceptions. However, almost everything needs to be heated again. The galleys on airplanes don’t have microwaves, and instead, they use convection ovens – which can result in the food getting overcooked, since the temperatures vary from one aircraft to the other, and if the plane happens to hit turbulence, for example, it can be a problem.
