In May I bought super cheap tickets to Poland (for June) where I saw FR kept cancelling/postponening the resumption of flights. Sure enough, cancelled by FR a few weeks after - and I rebooked for much more expensive Spain flights. Now it is more difficult to predict because I believe FR is operating most routes by now.

My tickets to BUD in late June were not cancelled though so these tickets were lost (I didn't want to rebook and pay much higher fare); not a big loss. At that time Hungary had really strict entry rules, but I guess I forgot that Fifa Euro Cup matches were played in Budapest at that time. Anyway it was only two 5 Euro tickets.
