Well ,when I went to ticket this in CAI it all went bad.

The two transit points in Asia was disallowed (see other post), but more concerning the Dublin desk would not allow me to end in AMM after having commenced in CAI. I managed to get them to recognise the exception that allows for ending in two different cities in Middle East but she indicated that this meant they treated CAI & AMM as the same place? and therefore I was transiting the origin city more than allowed? (said I couldn't have it both ways!)

My DONE4 has ended up like this:

CAI-xLHR-xHKG-PER-HKG-NRT-LAX-DFW-JFK-YHZ-JFK-xLHR-xAMM-KRT-xAMM-CAI

I had to pay $400US for AMM-CAI as an additional segment and yet I will not be using it as I have another flight out AMM back to BKK. I also had to book KRT-xAMM-CAI as a transfer to avoid a stopover there and so will have to convince the check in staff in KRT not to send my bags through to CAI as I intend to ditch the final sector. Does anyone have any experience of what happens if you no show for the final leg of a xONEx. The CSA said there was no problem with this???

Trully a bizarre situation and not happy about paying an extra $400US
