It seems to me that some people would prefer a return to the "glory days" of aviation when people actually got dressed up to fly, gourmet food on all flights, etc.
If I fly Ryanair, I know what to expect. They get me from A to B. Yes, they play cheesy announcements (especially the trumpet one when landing on time) but I could not give a fig for a sector of 1-2 hours.
The rules of the company are so well publicised that I fail to see how anyone can continue to complain.
