United Upgrade To First Class

Upgrading to First Class on United Airlines can enhance your travel experience with added comfort and amenities. To request an upgrade, MileagePlus members can use their frequent flyer status to access complimentary upgrades based on availability, especially for Premier members. Upgrades can be requested during the booking process, at check-in, or via the United mobile app. Additionally, travelers can bid for upgrades through United’s bidding system or use miles to secure a First Class seat. It's important to check the upgrade eligibility when booking and be aware that upgrades are not guaranteed and depend on availability.
