Ticket said be at the airport 2 hours prior to the flight, I was there 2.20 before and missed my flight.
Endless lines just to get into the airport, again at check in, then at passport control and finally security.
No help from the staff, who said I should have been here earlier.
You need 3-4 hours to reach your flight.
Hopeless...
