I think econ tray food isn't going to be great on any airline. C should be nice though, especially if they also carry this Rioha which was one of the better wines I have had up in the air. I've only had the econ wine on intra-European flights and it wasn't very good (especially considering I had to pay for it).

As for YEG, I almost took that connection during the late 90s. I was actually surprised as I never heard much about Edmonton (apart from the hockey team) until I noticed it on LOT's route map.
