Etudia is a whole other animal and can take ages but you won't be using it to fly out of the EU on normal airlines anyway.
Perhaps this is where the prob lies. There is one abnormal airline which flies from 'Chopin'...... Centralwings! This is what I usually fly with and believe me the situation in the Centralwings queues is the same as all the mayhem in Etiuda! Last time I flew with them the flight was delayed for over an hour because of the f@ck ups at check-in. The queue actually stretched outside the airport as they tried to get people for three different flights into one queue
On the other hand I flew with LOT a few weeks ago and there were no queues and everything ran smoothly.
Plus, why are there the huge queues to get through security after the passport control. I have stood in lines the length of the whole duty free corridor with hundreds of lost and confused looking souls wondering what the hell is going on!
