Can i use us dollar at hongkong airport?

You should have no trouble using US dollars at the bars in the Hong Kong Airport.

They’ll be happy to have your dollars. When you get your change, keep your hand out and they’ll give you some more because they’ll think you realized that they cheated you.

Do you mean you want to buy a bottle in the Duty Free? Or just have a drink at the bar? I’ve never tried to pay with a currency other than what was local, but mainly, I just take out my card when I travel. I’ve discovered it knows many languages and automagically converts to what every currency I need. For drinks at the bar, I would think they would take just about any of the big currency. Pounds or Dollars or Euros…..

Thanks guys. I mean to buy duty free goods. Sorry for the confusion

No problem at duty free.
