Korean Air Lounge
One of the best perks of having a credit card that offers Priority Pass is the access it gives you to lounges all over the world. If you've never been in an airport lounge before, you are missing out. It could make the grueling process of waiting for hours in uncomfortable and overcrowded airport gates less miserable.
I think the three biggest perks of lounges are; food, wi-fi, and the immaculate bathrooms.
Food
Free food and alcoholic drinks are a huge plus. It's even more fun when you can share drinks with friends. The quality of the food varies from each lounge, but for the most part they're pretty decent. It will save you about $10-$20 over buying food and drinks in the food court.
Instant ramen and booze.
While we speak, I am having some ramen and white wine. It's enough to kill some time before my flight boards.
Wi-Fi
Mpst places in the airport you go have pretty bad wi-fi, everyone is trying to use it at the same time. The internet connection in the lounge is usually good enough to do some work and not lose connectivity. It's also great to download some last minute audiobooks and podcast before your flight.
Bathrooms
Lounge bathrooms are pristine. Marbled counters, cleaned regularly, and often times has showers so you can freshen before a long flight. If you never took a shower before a flight, it feels amazing!
Even if you don't have Priority Pass, sometimes it's worth it to treat yourself if you have more than 2 hours to kill at the airport. But seriously, get a credit card with Priority Pass, it will change the way you travel.
