I thought that all T5 outlets did picnic bags however I was in the inaugural KRK flight on 01 May last year so went to Plane Food and for a picnic as the flight was a dreaded brunch service with an 1150 departure. I was told that they no longer did the picnic boxes they stopped sometime in April 2015 and hadn't updated the website...

I wonder if they have re-introduced them. I got one a couple of years ago and it was amazing but the bag was orange.
