Idiom:  Layover; used as a noun.

Example:  

“We had a three-hour Layover
in Korea during our airplane trip from Los Angeles to Bangkok in Thailand.  As a result, my total travel time from Los
Angeles to Bangkok was over 18 hours long! 
That’s what happens when I buy cheap airplane tickets!”

Meaning:  Layover refers to the stop in one or
more cities that one makes when traveling by airplane.  In this example, the speaker had a 3-hour stop
in Korea during his flight to Bangkok. 
As a result, the overall travel time included both his flight time along
with the time he had to wait while changing planes in Korea.  This idiom can be used to describe an air
travel situation that has 1 or more scheduled (or unscheduled) stops in their
itinerary.

This idiom is from the book “The Slangman – Guide to
Street Speak 1,” which is used as supplementary Idioms material in LSI’s Intermediate
Conversation classes.
