Airlines charging pax who 'buck the system'?
As we all know, a return is often cheaper than a one way.
With the LOCO's this doesn't apply, but I've just found a situation, whilst looking at helping a friend of mine to buy a ticket home (Europe to SA), where a one way would cost 4 times more than a cheap return. He has no intention of coming back and would simply ignore the return coupon.
In theory, if the passenger no-shows for the return flight, the airline is entitled to collect the difference. I have heard of a case where a business travel agency whose customer bought returns and never used the inbound segment, received ADM's (agency debit memos) from the airline for the difference.
Has anyone heard of a case where a passenger books on the airline's website, or through an on-line travel agency, and is subsequently charged through their credit card for the difference in such a case?
