Tips for Maximizing United Upgrades

Understand Fare Classes

Not all tickets are upgrade-eligible. Premium economy and full-fare economy tickets typically offer the best upgrade options.

Book Early

Upgrades are more likely to be approved when you book early. United often opens upgrade windows up to 120 days before departure for elite members.

Use Waitlist Strategically

  • If an immediate upgrade is unavailable, join the upgrade waitlist.

  • Higher elite status increases your chances.

  • Check regularly for inventory changes.

Combine Miles and PlusPoints

In some cases, combining miles and PlusPoints for an upgrade may offer better value, especially for international flights.

Real-World Examples

Domestic Upgrade Scenario

A traveler with Premier Platinum status flying from Chicago to Los Angeles:

  • Economy fare costs $400.

  • Upgrade using 15,000 miles or 10 PlusPoints.

  • Upgrade request submitted 90 days in advance has a 70% success rate.

International Upgrade Scenario

Premier 1K member flying New York to London in economy:

  • Economy fare costs $900.
