We originally booked a flight from Lufthansa from Lyon (France) to Honolulu with a connection at Vancouver Airport. But our flight from Vancouver to Honolulu has been cancelled and replace by 2 flights Vancouver > San Francisco > Honolulu and the connection time at San Francisco airport is only 50 minutes.
We are concerned about connection time and US customs/immigration...
I've read that US custom and immigrations can be done in Vancouver, if so I think we just need to rush out to the next plane (same terminal, same company)
Will 50 minutes be enough ? If not what should we do ?
Lufthansa keep telling us that if they made these changes then we should be good.
