The taxes are 'abusive' because they are sometimes very carefully "hidden". Ryan Air is wonderful compared to the nightmare called WizzAir.
The issues with WizzAir:
-Administrative fees of 9 Euro on each flight, for each passenger.
-Trolley bag (10 kg) an extra of around 60 Euros.
-Want have the same fare for 48 hours? Pay an extra 12 Euros.
-After that, checked in bag, is around 40 Euros per flight.
-Check in at the airport costs around 40 Euros.
-Online check in costs 5 Euros, and the say they mail you the tickets two days before.
-They don't mail you the tickets and they don't say anywhere you can only print the tickets on the same day of the flight (atrocious if the flight is at 6 am).
-You can get a refund for a cancelled flight, but the refund link cannot be found on their site. You have a post on Trip Advisor that points to that site.
-If you have paid for a small check in bag (10 kg) but bring that bag to the plane that's an extra 58 Euros (I can live with that).
-The boarding queue may stop for around 15 minutes, because a client needs to pay 58+58 Euros and the boarding attendant is unable to calculate such a complicated mathematical operation, needing the intervention of another boarding attendant (busy). That is a big no NO!
-Of course the web site has "bugs" and you may encounter "issues" that may force you to restart your session, specifically when asking for a refund...
-The "bugs" do not depend on the browser, or the OS (tested on Windows, OSX and Linux).
