On a recent trip to Europe, my United connecting flight from PSP to LAX was 4 hours late and i missed my Swissair flight to Zurich. United put me on a later Lufthansa flight and i finally got to my destination, Lisbon. On my Return home from Barcelona when i got to the Swissair check in, they had canceled my reservations. I guess they figured i never got there. I made these reservations 9 months in advance so i could have my choice of seats. my wife and i had to return home on stand bye. Do i have any recourse?
