As mentioned above, the No 1 lounge is currently closed for refurbishment, and I think it's moving locations, so there may well be windows in the new lounge... The "hot meal" used to be something like a fish finger wrap, with one fish finger. Having said that, I think the BA lounge has started doing limited hot food at mealtimes
The last time I flew QR ex-EDI, they didn't pay for Fast Track departures. Has this changed?
