I have flown with Regent a couple of times between Dhaka and Chittagong and Cox's Bazar and in general have found them to be OK although the air conditioning on their Dash 8 aircraft frequently doesn't work. However more recently I have twice flown with Regent on their new 737-400 aircraft fro Dhaka to Bangkok. However when they say new this actually means new for them as both aircraft are leased from other airlines and are actually starting to show signs of age. Only one of them has an onboard entertainment system which didn't work when I was on board and the other (seemingly older) aircraft actually still has ash trays in the arm rests which have been taped up to stop people from using them but on a lot of the seats the ash trays have been removed leaving a rather sharp and dangerous metal edge on the end of the arm rest. On my last trip from BK back to Dhaka the Pilot went AWOL and so were almost 2 hours late leaving BK. The meals on board are very typically Bangladesh and not good and of course you cannot get an alcoholic drink on board. The tea and coffee is also pretty bad. The FA's are for the most part friendly enough but efficiency is not their highpoint. However despite their shortcomings their prices are very good.
