Flew out of Split airport on a Saturday evening. Queues everywhere and departure lounge in particular was bursting with people. There was vastly inadequate seating and not even enough floor space for tired passengers to sit on without causing an obstruction to others. I couldn't believe how many more passengers were allowed to pour in when there was clearly inadequate room for existing passengers due to flight delayed caused by weather. When passengers were finally called to gates they were left standing for a good 30 minutes before a member of staff began to process the enormous queue that had built up. Our gate number was changed at the last minute and it took ages to work our way through the crowds to join the long queue. Once through the gate we waited an equally long period of time queuing for the airport bus on the hot stairwell. My overall opinion is that this airport does not have the capacity to cope with the volume of people coming through at peak periods. Even taking into account the delays due to weather I struggle to see how this airport has enough seats public toilets (no toilet paper in any of ladies toilets) food and drink areas for the numbers passing through. Incidentally the first mention we had concerning the cause of delay was when the pilot announced this was due to bad weather in Europe just prior to take off. All airport staff looked stressed and fed up. It has well and truly put me off using Split airport ever again.
