Pros: The staff were amazing considering we had an hour and a half delay and checked in to the flight manually! I felt bad for them actually, as it clearly wasn't their fault, but they are on the front line and had a deal with some very upset customers.
Cons: I had to stand in line for and hour and a half while the staff tried to figure out why the computer system wasn't working. When the system decided that it really wasn't going to work, we had to check in manually, which doesn't seem very safe to me! I had a handwritten boarding pass, and luggage label! The flight was then delayed further and we ended up being and hour and a half delayed. Again, the staff were amazing with what they had to deal with, but I do wish that there was a representative from Thomas Cook to talk to us while we were in line at check in. Tanoy announcements didn't cut it really.
