Our CC aren't allowed checked bags on Shorthaul but I know some of our longhaul CC do the same on short longhaul trips, either for reasons of economy or because they don't trust the local food...
TBH if the suggestion is the only way crew can guarantee a sensible diet is to drag half of M&S around with them then the flight and cabin crew side of the industry is farked. Can you imagine the office staff being told to bring a suitcase of food into work (and that's not a pop at office staff, just a comparison)?
Anyhow I'll leave it there and wish our Company Council had been more robust in their response to the EASA regs... so back to flying hours and best of luck to the Easyjet pilots....
