FL310. .Agree with your comments, however FYI, Indian Airlines has been flying to Dubai from Hyderabd for some time now. Also in case you are not aware,guess who is Sharjah's biggest user, Indian Airlines, no less!. .Incidentally the attempt to open the door was not delibrate according to news reports. The pax was a first time flyer who apparently tried out the instructions given without realising it was only for emergencies. The guy next to him watched but did nothing. Indian Airlines is quoted as saying they will not take any action against the pax.
Cheers. .TK
