Filion:
Are you perhaps over 60? I left with the required service length but I am under 60. There is no "other airline info" tab that I can see anywhere on TRIPS at the moment. I can only access EK flights now but I have been given the impression that "other airline" access will appear on TRIPS once I hit 60.
This access is eagerly anticipated for the reasons you mention so it would be interesting to see if anyone here has experienced what I am describing.
