I chose Go because they offer the cheapest tickets from Czech republic to U.K. My previous experience with this airline was OK, just annoyed me with delays.

Boarding started on time, I was satisfied that we didn't have any delays. I was really surprised, when our Boeing 737 stopped on the runway and didn't move. After a few minutes the captain told us, that there was some technical problem with pressure indicator and we must go back. Well, we returned; the plane was parked near the maintenance building and we stayed in the plane. Almost from an hour we waited for repairs to the plane and we took off from PRG with more than 1 hour delay. Flight was calm, but the crew (stewardess) were reserved and little bit hissy. Landing OK, the airport staff, check-in at Prague and baggage claim - no problem.

Return flight from STN to PRG was smooth, took off on time. But there was a long and annoying queue for security check at the Stansted, which was tiring.
