Domestic terminal only IIRC? The staff at the domestic arrival lounge is excellent, with the younger lady (Tam?) working there one of the two best IC Danang staff I interacted with.

The contract lounge used by airlines in the international terminal is... completely unexpected for DAD. Vast, obviously new, ultra-modern, stylish, usually almost empty. I seem to recall a shower stall in the posh WC. This facility is physically a world apart from the airport lounges I have visited in HAN and SGN, although its F&B offerings are similar. Unfortunately it is not Priority Pass affiliated yet. It reminds me of a showcase a city would build for something like the Olympics, completely underused before, and hopefully not after.

The exchange rate at the booth in the international terminal was, in retrospect, very reasonable, with little of the usual airport markup, at least for USD. The one in the domestic terminal was closed both times I was there.
