Even though Indian Authorities are notorious for being tough QR wouldn't face too much of a hurdle. While I seriously doubt that QR will get all that they demand which doesn't only include new destinations but also more seats to existing destinations QR will at least get two or three more destinations soon. This is for four reasons.
- The current ASA between Qatar and India has some rights that are allocated to GF which will be transfered to QR. I am not sure but I think they include MAA.
- Indian Carriers currently offer more seats on India-Doha flights than QR is allowed too and the upcoming talks are supposed to level the playing feild.
- The local Indian population has been very active in Lobying the Indian authorities to allow for more flights so that prices could be reduced.
- A source from the Aviation Authorities told me that India is taking a more relaxed approach to Aviation which should see more rights given to more airlines in the region.
I also can't think of more destinations than what you already have listed, but it doesn't really matter because at most they will most likely only get 3 destinations.
Tokyo was mentioned by the Kuala Lumpur Local Manager but it doesn't appear on the destinations pipeline for 2003.
