United Explorer vs. The Platinum Card: Head to Head

Lounge Access

The United Explorer Card gives you two United Club one-time passes a year. The Platinum Card's Global Lounge Collection spans more than 1,550 lounges, including Centurion Lounges and Priority Pass locations, so it wins easily if lounges matter to you.

Rewards and Redemption

The Explorer earns United MileagePlus® miles, which are most useful for United and partner award flights. The Platinum Card earns Membership Rewards® points, which can transfer to 20 airline and hotel partners or be used through Amex Travel.

Airport and Travel Perks

The Explorer focuses on the United trip itself: a free checked bag for you and a companion, Group 2 boarding, and 25% back on inflight purchases. The Platinum Card spreads its value across lounges, hotel status, and credits for hotels, Uber, dining, and entertainment.

Annual Fee

The Explorer has a $0 intro annual fee for the first year, then $150. The Platinum Card's annual fee is among the highest on the market; see the card details above for the current amount. Neither card charges foreign transaction fees.

Who Should Choose the United Explorer?

Who Should Choose The Platinum Card?

The Platinum Card suits frequent travelers who fly a mix of airlines and want lounge options in more airports, plus Marriott Bonvoy and Hilton Honors status. It makes the most sense if you will use several of its credits each year.

Tips for Application Success

Before You Apply

• Check your credit. Travel rewards cards generally go to applicants with good to excellent credit.
• Count your trips. Estimate how many United flights and checked bags you have in a typical year.
• List the credits you would use. Only count statement credits you would spend on anyway.

Application Strategy

• Know the issuer. Chase and American Express each set their own rules on welcome offer eligibility.
• Time your application. Apply ahead of a large planned purchase so you can meet any minimum spend naturally.
• Enroll in benefits. Several perks require enrollment after approval.

Our editorial team checks card details against issuer sources. You can also explore the full dataset yourself in the Kudos Card Explorer, where more than 95% of cards don't pay us commissions.

Frequently Asked Questions

Which card is better for lounge access?

The Platinum Card, by a wide margin. It includes the Global Lounge Collection with Centurion Lounges and Priority Pass membership (enrollment required), while the United Explorer Card provides two United Club one-time passes a year.

Can I use Amex Membership Rewards points for United flights?

Membership Rewards points transfer to 20 airline and hotel partners. Check the current partner list before you transfer, since you would need a partner airline that can book United flights.

Should I get the United Explorer Card if I don't fly United often?

Probably not. The Explorer's main perks, like the free checked bag and priority boarding, only apply on United flights. If you fly several airlines, a flexible travel card may give you more value.
