The flight from Helsinki to Toronto was very cramped. No leg space and no room to even walk. Very bad experience

Our checked baggage was not transferred correctly so now we are stuck in Budapest with out essential luggage. We are not able to get much help from FinnAir because their service from Seattle is on periodic.
