Arrived at the airport terminal 2A and got a shock to see the unbelievable huge crowd at Star Alliance check-in. The end of the row was at the entrance of the airport. Seems LH and AUA don't really care of this situation weeks ago I was waiting 25 minutes for drop-off in the same time. I will think twice to use Swiss if check-in will be pooling into a big maze. Security improved a lot not waiting for long and they were friendly. Airside hard to find any free place to sit down on that Saturday afternoon restroom was clean. Many announcements were not clearly understandable thus I nearly miss my flight.
