I canceled the flight but not wizz nor kayak replied to my messages. Worst experience from both

Timely departures and arrivals. The seat was slightly forward leaning which made it uncomfortable

There were not enough staff and signage to direct people to Wizz Priority lanes for check-in and boarding. It didn't feel like we were Wizz Priority holders.

Boarding was fine, crew professional but not very friendly. Seats are very tight & uncomfortable. 1h delay due to crew change and mechanical issues - no communication whats going on.

Crews are great, chill, good snack sets on offer, I didn't feel they play any annoying budget airline games. I will probably fly with Wizz every chance I get it

The flight was delayed again. I had a bad experience with Wizz Air, and I don't want to travel with them again.

Very very very…… uncomfortable seats /does nor reclain/ and so little space /this was 5:30 hours flight- and quite expensive no longer low cost airline/ 5:30 hours flight and no water or snacks was offered anly very expensive sales.

Got rejected to enter the plane because i took calming pills. Im scared of flying and i always take it since 12 years and it was never a problem with other airlines.

The flight was 1.30 hour late because of the Police checking 4 passengers. This was not Ryanair fault but was quite ennoying.

Very aggressive clerk at the boarding gate. Forcing people to pay for baggage’s that actually fit into their small cage
