I agree that one breakfast is fully sufficient - but I must say that OK does make certain in some way that you get some different on each flight. Now I usually take a pass on one of the two as they tend to be close to each other, transfer times in Prague being rather short and the flights themselves not longer than two hours in general; on a recent two day return AMS-KBP-AMS (via PRG) they had four different meals - two of which were quite edible. I agree about the breakfast not being their strongest point - but could it have been the catering out of DUB?

Oh - and in further comment on my OP: today they didn't ask me to sign a waiver.

In CSA they indicate your eligibility for an upgrade with the SPML indicator in the reservation - it is just SPML - without indication what type of is meant. I suppose the number of people with that indicator is a good prediction for the number of C-meals they need. I wonder whether it was the fact that last time I checked in over the Internet for my flight ex PRG in Economy. Does that reset your SPML indicator (because they assumed that I did not want an upgrade?). Now I didn't do an Internet check-in today and there was no problem - not that that means a lot. But Internet check-ins for CSA Elite members ex PRG who want to get upgraded are useless anyhow I later realized.
