Never used Wizz Air before. Are they good?

Hi everyone.

I'm planning to go to Gdansk in May and noticed that Wizzair fly from there to Turku in Finland where my sister lives (it's usually quite hard to get to, as usually have to fly to Helsinki instead). So we thought we would maybe go and see her for a couple days.

Looking online I've seen that Wizzair seem to change flights date and time quite a lot?

We would be staying in Gdansk for 4 days before flying to Turku for only 2 days and then back to the UK through Helsinki with Finnair.

If the Wizzair flight ends up being changed to a different day it would really affect the whole trip.

People that have used Wizzair recently, are they changing flight dates and cancelling flights more than other budget airlines?

Thanks.
