I need your advise. I was supposed to fly to CCU from IAH on SQ in July, but now have to change my dates. I just checked and saw that Qatar's price in Y has come down and now it is an option as well. The advantage is that QR's layover in Doha is really short compared to over 8 hrs for SQ. Also, the flight duration for QR is much shorter even though both are ultra long hauls. SQ flies through DME. I am not super fond of flying through DME. Also, I have never flown with QR but have flown with SQ few times. I love SQ's product and I am unfamiliar with QR although I know QR is very good. Any suggestions or pointers?
