Plaza Premium airport lounges are mostly found in Asia, but are also in the Mideast, UK, Canada and Brazil.

Airlines often contract with them for lounge access, so business class and sometimes elite passengers are welcomed. And you can access many of the lounges with a Priority Pass card which comes bundled with many US premium credit cards.

They also operate lounges, such as the SkyTeam lounge and the American Express lounge in the Sydney airport.

And Plaza Premium has a loyalty program where you earn points for lounge visits — even when those lounge visits don’t cost you anything, because you’re an eligible business class customer or use your Priority Pass car for entry.

The program is Arrture, Airport Travel Rewards. You join in the lounge, ask for a membership application on your next visit.

Every 20 lounge visits you earn a free lounge visit. If you’re accessing these lounges with a Priority Pass card (versus paying in or getting in with a business class boarding pass but sometimes fly economy) this is still useful.

• You can give the lounge pass to friends or family
  
• You can use it to guest someone into the lounge, since not all Priority Pass cards come with free visits or guests.

Members also receive 15% off paid access to their lounges and 15% off treatments in lounges that have spas.
