I’m flying with RyanAir for 25€ for a round trip (Eilat, Israel)

I’m just regularly checking RyanAir’s website and other sites like momondo and basically just checking what’s available. Most of the times RyanAir will fly from kind of deserted airports so be ready to pay something to get there (Train in my case).

It’s also a lot of timing. It’s not holiday season so the AirBnbs are reasonably priced.

And you need to be spontaneous, sometimes there’ll be super cheap flights but they will be gone if you don’t just buy them.

I just checked on RyanAir’s website and there is a flight from Berlin to Billund (DK, Legoland) for 3€.
