Buying OneWorld tix via AA.com
 

Just an observation, don't know if anyone can shed any light on it or has any comments.

I normally buy my OneWorld tix on AA.com, various reasons, mainly though that it bills me in GBP if I want, I like the flight search and choose functionality and it normally spits out the same results as ITA Matrix, i.e. I can find a OW flight on Matrix then I can find it and buy it on AA.com

Odd thing happening today though, Looking for some discount economy tickets from MAD-LHR, best price Matrix came out with was €306 (about $434) which is €120 more than the inventory that all the other sites has.

Anyone know how come ITA and AA has fares in V, whereas expedia, iberia.com, travelocity etc all have fares in O?

Possibly that the other fares have sales restriction which do not allow AA to sell them
