I picked up a super cheap expedia CX ticket LHR - HKG - BKK - LHR. I'm trying to find the fare code and rules. I can't find it anywhere on Expedia, its not on my e-ticket. I contacted expedia to ask for the fare basis and they sent me the PNR and are insisting thats it.

Any ideas how to find out the fare code?

On a side note my plans have already changed as CX seem to have cancelled the CX253.
