I am booking a WN flight which will be a connection from a British Airways flight. Entirely seperate tickets, of course. And I realize neither BA nor WN are responsible should BA be late and I miss the connection. My question is: Should I miss the connection, will my non-refundable WN ticket be worthless or will they allow me to apply it towards the next available flight (I realize at a higher fare)? I know they let you use the unused value if you cancel before the flight departs, but just want to know what the policy is if I am unable to call them before departure.
