I am amazed at how difficult it is to contact the IC portion of AI. I have a webticket (in D class) for an IC operated flight in a few months. When you call AI they deny that it is even possible for a PNR to start with "R". It is one thing if they want to say "Oh, that is our IC branch, you need to call India directly." But they act as though it is impossible to have such a PNR.
