Best/cheapest card for lounge access?

As someone who travels a lot, what is the best/cheapest card for lounge access?

One of the best cards for lounge access would be the Chase Sapphire Reserve. The card gives you access to 1,000+ airport lounges in the world, so if you’re a frequent flyer, this would be good for you. The card itself has an annual fee of $550, which is quite high, but you do get $300 in travel credit each year, so the total cost would only be around $250.

The Hilton Honors American Express Surpass card is another option. It gives you 10 Priority Pass lounge passes for an annual fee of $95, and the Priority Passes work at 1,000+ lounges around the world as well.

I second the Chase Sapphire Reserve Card. However, if you are looking for a good lounge access credit card that does not have an extremely high annual fee, I would recommend the American Express Green Card. It has an annual fee of $150 and enables you to purchase lounge access through LoungeBuddy to any of the lounges in the LoungBuddy network without having to be a member or have first class tickets. While you still have to purchase lounge access, you can get up to $100 in statement credits annually on your LoungeBuddy purchases. Furthermore, the card has no foreign transaction fees and offers other travel related perks.
