Hi all. I've found a variety of relatively cheap fares/routing using ita for a multiple-city OW ticket Europe - NZ. however while kayak/orbitz can be persuaded to 'price' my ticket I am unable to actually confirm - I seem to always get a "We're sorry, due to changes in availability, we're unable to confirm your selection with the airline. Please make another selection." message Does anyone either know of some way in which I can price this ticket/get it purchased, or can definitively determine whether the proposed routing is invalid. (edit: The itinerary is DUB-CDG-CAN (stop) CAN-PEK(stop) PEK-AKL - in august 2011) I am able to reproduce the issue using multiple dates/flights, so it is categorically not the case that it is related to any 'actual' changes in availability. I am also separately able to reliably price an itinerary in ITA (on a different airline, for a different itinerary) which I am unable to buy from the selected airlines website - the airline in question(Aeroflot) seems to ALWAYS show the inventory as one category 'higher' than ITA does. e.g. if ITA says T is available then http://www.aeroflot.ru/eng will show U availabiliy and so forth... in my examples it means that ITA is systematically 'out' by US$100 on every flight priced as opposed to the airlines own website. any help would be appreciated. I am of course happy to post the entire routing and fare rules from ITA, but was not sure if that was appropriate as it is possible that this is an FD.
