I was a little disapointed with the Miami episodes. The LHR
show was great, lots of stories of actual airport workers, mixed in with some good customs and customer stories. This one made it look like the US carriers didn't want to do anything on camera with the producers.
However, I would watch the Airport series at LHR
anyday over the "Airline" crap A&E has on. But I would bet there's a US show in the works somewhere after the success of Airline.
