I missed it. I should have gone with my first guess, but then "analysis" suggested it would be what is served on an airline. (I think that I've only had one meal on an airline, and that was a long time ago.)
You're not missing much even the meals in first class are mediocre these days. On many of the airlines you get charged for a snack that's dreadful, so many people buy some fast food in the airport and bring it on board.
At least if I have to fly through Midway I have a choice between a good Chicago hot dog (with a poppy seeded bun) or an Italian beef sandwich.
