• You can earn 3X points on the first $6,000 spent annually in combined purchases at grocery stores, gas stations, and on dining.
• The anniversary free night award, valid for a stay of up to 35,000 points, can provide value that easily outweighs the card's $95 annual fee (publisher-formulated estimate).

‍

‍

• A significant welcome offer to jumpstart your rewards.
• An annual free night award provides ongoing value year after year.
• Automatic elite status and strong earning rates on everyday purchases help you maximize travel perks.

‍

Cons

‍

• An annual fee applies and is not waived for the first year.

Marriott Bonvoy Boundless® vs United Explorer

‍

Categories

‍

Deciding which is better United Explorer or Marriott Bonvoy Boundless comes down to your specific travel habits and loyalty preferences. Each card is tailored to a different type of traveler, offering unique perks for either airline or hotel loyalists.

‍

• United℠ Explorer Card is designed for frequent United Airlines flyers. It's best for travelers who can take advantage of United-specific perks and airport security benefits.
• Marriott Bonvoy Boundless® Credit Card is ideal for frequent travelers who regularly stay at Marriott properties. It suits those looking to maximize hotel stays and achieve elite status within the Marriott Bonvoy program.

‍

Redemption

‍

United℠ Explorer Card: Points are redeemed through the United MileagePlus program, primarily for flights with United and its airline partners. They can also be used for other travel purchases, such as hotel stays and car rentals.

‍

Marriott Bonvoy Boundless® Credit Card: Points are best redeemed for free night stays across Marriott's extensive portfolio of hotels. You can also transfer points to dozens of airline partners or use them for exclusive travel experiences.

‍

Travel Perks

‍

• Primary Ecosystem: The United Explorer Card is built around the United Airlines and Star Alliance network, making it an airline-centric card. In contrast, the Marriott Bonvoy Boundless card is centered around the vast global network of Marriott Bonvoy hotels.
• Booking and Redemption: You'll use the United portal to redeem MileagePlus miles for flights and other travel. With the Marriott Bonvoy Boundless card, points are redeemed for hotel stays via the Marriott portal, but they also offer the valuable option to transfer points to dozens of airline loyalty programs.
• Lounge Access: A key perk of the United Explorer Card is the inclusion of two one-time passes to the United Club each year. The Marriott Bonvoy Boundless card does not offer lounge access, keeping its focus on hotel-related benefits.
• Foreign Transaction Fees: Both cards are excellent companions for international travel, as neither charges foreign transaction fees.
• Airport Security Credits: The United Explorer Card typically includes a statement credit to cover the application fee for programs like Global Entry or TSA PreCheck, a benefit not offered by the Marriott Bonvoy Boundless card.

‍

Its key benefits, such as a free first checked bag, priority boarding, and two annual United Club℠ passes, directly address common pain points for regular travelers on the airline. Additionally, travelers who can take advantage of the statement credit for Global Entry or TSA PreCheck® and the lack of foreign transaction fees will find this card particularly valuable.

Who Should Choose the Marriott Bonvoy Boundless®?

‍

The Marriott Bonvoy Boundless® is an excellent choice for frequent Marriott guests and value-conscious travelers who can easily offset the annual fee with the card's perks. It also appeals to status seekers aiming for elite tiers within the Bonvoy program and everyday spenders looking to accumulate points on gas, groceries, and dining. Ultimately, this card is best suited for those who can fully leverage the Marriott-specific benefits and want to earn and redeem points within its ecosystem.
