Reviving an old thread because it's related but involves an international inbound.... AA is giving me a 55 min conex time as "legal" - JFK-MAD-ZAG with 55 mins in MAD. I assume that I need to clear customs and go to another terminal making this near impossible not to mention it's the only flight MAD-ZAG. Any actual experience before I switch to a flight that leaves way before I want to leave with way too long a connection in MAD? ;-)
