Thanks KingCanute. Flight is at 18.10 and check out of hotel is 11.00. Given I will have been in BKK for a week, I just want to head to the airport on check out, so potentially have 6 hrs or so. Very helpful to know the QR lounge opening times. Was thinking that with CX and EK lounges also available, I could fill the 6hrs if I can check in early enough.
