When I started flying in the seventies, the choices really were beef, chicken and fish. Occasionally you would see the odd special meal. Now there is a bewildering array of meals. Low sodium, wheat, halal, veg, vegan, kosher, no nuts, etc etc etc. I wonder where it's going to end up? How many choices are there now? Luckily this is an information age so maybe we will be able to order specific meals for each flight. I feel sorry for the FAs though. As for me, I am allergic to nothing, have no religious issues so eat just about anything from any airline anyplace.
