flight to DFW lands in 90 min. It is 40 minutes late and he has a connecting flight to SLC 1 hour later. His flight to SLC is also a British Airways flight.
Does he have to go through customs when he lands in Dallas or does he wait till SLC? If he has to go through customs in Dallas I think there's a chance he misses his connection... Any of you with experience let me know what you think.
