I have a question that I hope some of you airline insiders would be able to answer.
When an airline flies from an international destination to more than one American city on the same flight, do the passengers bound for the second city have to get off on the first stop and go through customs, or do they wait until they are at the second city?
For example, a few years back, Delta used to have an MD
-11 that routed NGO
If a passenger was bound for Cincinnati, did they have to go through customs in Los Angeles, or could they stay on the plane until it got to Cincinnati?
If all passengers have to get off, then my next question that would follow is, What advantage does the airline achieve by offering "same-plane" service to more than one city from an international destination?
If international passengers aren't required to get off, then my question would be, how can they tell which ones need to go through customs and which don't at CVG
since the airline also picked up passengers from LAX
on the second segment?
I have noticed that these types of flights have been severely reduced since 9/11.
Thanks for any input you have on this issue.
