On a related question Jim MacKenzie writes that:
If you did this a lot, it's possible an airline might ban you from flying it
Likewise another question mentions that:
if you ditch they have the right to cancel the rest of the ticket, fine you and even ban you from the airline. Though the only times they would ban or fine would be for repeat offenders.
But have any travelers actually been banned with a particular airline for exploiting hidden city or throwaway ticketing in the past decade? Links to authorative references rather than hearsay are welcome.
Note that for the sake of this question simply banning someone from the frequent flyer program doesn't count. I'm only looking for cases where a person could no longer take a flight on a given airline for exploiting their pricing.
