I was to have spoken at a workshop in Bangalore this summer, and the organizers were planning on flying me on AI. They're having to re-plan for sometime next year. Thanks to all the informative and factual posts on this thread, I know to strongly insist on NOT using them, no matter how much cheaper it is...or to negotiate a "I'll book the airline myself and pay whatever diff. b/n that and AI". Even if it costs me another $200 or so out of pocket, it sounds like it's worth the difference.
