I had to travel through the Qatar Airline fr om Houston to Chennai. After 14 hours of travel the airplane landed in a Deserted. We were made to get down the stairs. It was difficult for senior citizens and parents carrying the kids. Once we are in the bus most of the passenger needs to stand for more than 20 minutes. Since the transfer time is less we need to run for the security check wh ere they treat everyone strange. Then we need to rush to gate and wait in long queue. After getting the boarding pass we need to wait for the bus in a bus stop. It was so sultry. Hope you can imagine the heat without air-condition in the desert. Again we need to travel in the bus for 20 minutes to reach the aircraft. I am not sure why the Doha airport is not using the air bridge which is been used in all most all the international airport.
