Im surprised it's all economy that is having inclusive catering removed. I was expecting a 'last class' but those with full or semi flexible tickets will get something. A bit like what germanwings, air Berlin and Brussels Airlines have. Or a Virgin Australia style system whereby you get what you're given for free but can buy something more substantial.
It's a little disappointing that on UK domestic we won't get anything at all. Even if we have paid a lot to be on a fully flexible ticket.
