Thank you VintageKrug for addressing the issue. I only contact the airline to check the validity of the ticket not the source. If you notice I havent published the name of the web site re my latest ticket, but £1700 return for AY and BA in business is a very good deal.
I am still curious though about the code share prices for BA/QF.
I do not understand how BA can have 2 different prices for a flight going to the same destination being advertised with BA flight numbers (irrespective of it being a codeshare). The outbound price is exactly the same, its only the inbound price that differs. Yet through 3rd party sellers, (i.e. web sites) this differential doesnt occur. I know pricing is complex, but I would have thought that thorugh the airlines own web site, these differentials would not be so blatant.
