OW is a neat little alliance with 13 members. The EU and US members of OW are all in an (approved) cartel and hence are allowed to peek into each others books. *A has 28 members, and not all the *A partners have ATI, so LH & co are not allowed to see what e.g. TK,LO,SK,TP, etc are pricing across the atlantic. So mutual authorisation is very unlikely to happen. *A is pushing its members hard to all use the CITP developed with Amadeus on its Altea platform, but United, Turkish, Air India, Air China and others refuse to join it. OW has amanged to push all but AA onto a similar Amadeus system, ST is on a similar path (except of course for DL who wants its own CRS).
