I suggest not to use MMT for flight booking. Recently I had a very bad experience. Although I selected window seat & paid for it while booking the flight in MMT, but a different seat was allotted. The entire seating layout of the AI803 flight is completely different to what is shown here. And this is not the first time. This happened to me thrice continuosly in a span of 1 month. Initially I thought it was a mistake with Air India. But, this was due to no interaction b/w airlines & MMT.
