No need to be embarrassed by AY as their flights and service are good; many people fly with them and some choose them over QR! If open you are able to use the QR lounge anyway. I think I flew from BKK once and used the QR lounge. It was however a long walk from the lounge to the gate. Mind you, everything is a long walk at BKK.

And well done in owning up, I muddle flights and destinations too! I guess others do to, more often than they would admit to.
