Check-in at LTN seems to become an absolute nightmare. It's chaotic. Saw passengers that were queuing at the right desk, already waiting for 45 minutes, when they could start queuing again, cause their flight has in the meantime been switched to the last minute check-in desk. This also happened to me on another flight. One third of check-in desk were closed. That's ok, if there's not much traffic, but not during "rush hour" and passengers queuing up until to the arrival hall. Flight more than two hours delayed but were told only after already checked in and afterwards refused to change flight ("You have already checked in..."). Normally I do not bother too much about delays. They happen. But expect to be better informed, especially, if it's an evening flight and the delay is such, that many passengers miss their onward trainride in GVA as was the case this time.
