The end of economy-class plane food?

Passengers flying via Heathrow Airport now have the option to take on board ready-to-fly picnics.
Instead of often nondescript tray meals, people can now chow down on take-away boxes prepared at one of the airport's 70 restaurants, which include Gordon Ramsay's Plane Food, Caviar House and Strada.

Whilst it was introduced a few years ago at T5, the service is now airport-wide. Caviar House is probably the coolest—meals come within an ice compartment.

Beats most food offered in coach class.

All food boxes are said to be fitting nicely in the overhead compartments, and since this service is mostly used by long haul travelers, it shouldn't add up to the overhead wars.
