(I am wondering why there is no airline base in Krakow, Poland.)
Simple answer. The airport is a disaster.
Wizz moved to KTW because of the primitive facilities for both for passengers and because of poor technical aids.
The new domestic terminal is basically a huge luxury office block for the managers and all their friends and relatives.The rest of it has about 3 check-in desks used by LOT but only 1 is being used because no demand.
Huge fuss was made about laying the foundation stone for the new fire station. Lots of speeches and BS.
The International terminal has not really been improved with most passengers held in boxes. There is still only 1 baggage belt for aircraft bigger than 50 seats.KTW will overtake KRK in passenger numbers soon even though it has less attractions and most pax travel to KRK by road.
The management also have discouraged charter flights over the years as being too low class. Charters are not displayed on the website arrivals board.
New Panorama restaurant with no windows etc.etc.
Three girls at the business lounge desk with only about 20 seats for pax.
I could go on and on.
