BUE-PTY. Arrived at Buenos Aires 5.30am for 7.30am flight and the line was unbelievable. Told by customer services that the flight was delayed so not to worry about a 1 hour wait. When I started to ask her about our connection being effected in Bogota she walked off saying she can't help. We went back 30 mins later and there was no one helping out and only 2/3 desks open operating very inefficiently. The flight did leave late and it took about an hour to dump our bags without any information but once onboard it was good new seats AVOD etc and the change over in Bogota was fine. FA's hopeless. I think it's worth paying extra for reliability.
