I start a DONE4 shortly, booked through the CX agent in Columbo. This has flights on CX, QF, BA, & AA
I have three record locators: Cathay's, Amadeus for BA/QF & AA's.
Check my Trip happily shows the BA/QF sectors, seat assignments etc. & I can use BA.com to assign seats etc for the BA flights. Same with AA.com; I can use the AA RECLOC to look at my AA flights, assign seats etc. .
However, I am unable look up my CX flights on the internet in any manner. I requested some assistance from the CX web site help desk and after a few emails to and fro I was advised by them that this will be the case unless I put my Asia Miles number against the flights instead of my QFF number.
