Passengers complain that they aren’t served food anymore in coach most of the time. When I first started traveling for business (and certainly growing up), passengers complained that they were served food. Because airline food was a joke.
Back when United’s premium cabin meals were branded with celebrity chef Jacques Pepin they actually had economy meals which were chef-branded. United’s chef in economy was Sheila Lukins.
Thirty years ago of course United had an economy meals partnership with McDonalds — with happy meal toys (I have both Ronald McDonald and Grimace). United replaced the galley carts with ones specially-designed to keep the burger warm while the lettuce and bun stayed cool.
