Some people love to travel and have no problem spending their day in transit. However, others see air travel as a means to an end and find the whole airport experience a hassle.

There are ways to improve the experience for these travelers, including heading to an airport lounge before your flight.

A membership with Priority Pass — a global network of airport lounges, experiences and restaurants — can be a good option to gain lounge access.

Let’s look at Priority Pass lounges, how they work and some key things about the program.

1. Multiple types of airport experiences are available

Priority Pass is most known as a worldwide airport lounge program, featuring more than 1,300 locations from which to choose. However, Priority Pass isn’t just limited to lounges — it also includes experiences and discounts for its members.

The types of experiences available will depend on the airport. At some, you can get up to $28 for you and your guests to eat at eligible airport restaurants. At others, this can mean complimentary spa treatments before your flight.

And if you’re on an exceptionally long trip, you may appreciate the private bedroom suites available to Priority Pass members.

Finally, even if there aren’t lounges, restaurants or sleeping suites available, Priority Pass options may be available as discounts at select stores.

2. Not all memberships are the same

Now that we’ve discussed all the options available to Priority Pass members, there is one crucial caveat: Priority Pass has several different membership levels, and they’re not all equal.

The cheapest Priority Pass tier that will grant you lounge access costs $99 per year, but you’ll need to pay $35 for each lounge visit.

The most expensive is $469 per year but includes unlimited, complimentary visits for yourself — though you’ll still be required to pay for your guests.
