Quote: I am ganesan As most of us are travelling between us and India I am sharing my experiance.i was in Canada and travelled from Toranto to Bangalore. The flight was at 9 .30pm dep and it reached Abudhabi by 8pm and again the flight at 9.30pm.As both flights were night I didn't get any canca to walk in the flight.also I had wheel chair Assistance so no walk in terminal also.At adabi I have to enter the flight by steps as the flight was in the ground.in the flight in my left leg blood clotted and had heavy pain after landing in Bangalore there was heavy sweeling and admitted in hospital and after treatment and 7lakhs bill 90percent ok and still it will take some months for full recovery.now I was told most people take blood thinner tablelets before travel.
