I found a ticket from SEA to Frankfurt for very cheap on British air. It also touches down in London. I am headed to Gothenburg so I would have to buy another ticket anyway. What happens to my ticket if I get off the flight early in London and don’t fly on to Frankfurt. And vice versa…what if I try to catch the connection in London on the return instead of Frankfurt? Do they cancel certain portions of tickets if you don’t use them? Please let me know ASAP! I don’t want to see these fares go away…thanks!
