Flew today from LIN connecting to PRG. The plane parked at 02E and therefore was bussed to 02F. Once I got off the bus, there were clear signs indicating the different gates to the left and to the right. The old passport checkpoints were still there but empty. Apart from that, F2 was overcrowded and the lounge had no seats available (not even in the lower floor). F1 seems to only have 3 operational jetways for now.
My connection was short and therefore couldn't explore any further...
Sounds like you've mixed up F1 and F2.
