Can't say I have seen any fares as low as Wizz fares from Ryanair to Poland recently.My one way flight on Tuesday to KRK was more than 100 pounds. The flight was not full, I think 118 pax although fairly full flights are quite common.
I don't know how Wizz make a profit with a 50 pound return trip of around 2000 miles not to mention the 30 pound fare. So at 30 pounds that's 1,5 pence per mile.Wizz must be doing something right or they would have gone bust by now.
I guess flying must be more economical than using cars buses and trains.
