What happens if you don't show up for a flight?
My wife recently bought a one-way ticket that, due to a change in schedule, she will not be able to make. The ticket cost less than the cost of a change fee, so she is going to abandon the ticket rather than move it. The airline rep (I forget the airline, think American or United) said it costs $150 to cancel a ticket (the ticket cost less than this).
What happens if she just doesn't show? We fly this airline with some regularity.
On a related note, what should one do with a cheap ticket (less than $150) they can't use, other than abandon it, when the change fee is $150?
