To upgrade your class with United Airlines, you can follow these general steps:

Booking a Ticket:
Ensure you have already booked a ticket in a lower class, such as Economy or Premium Economy.

Check Upgrade Eligibility:
Verify if your fare class is eligible for upgrades. Not all fare classes are eligible, and upgrades are often more likely for higher-priced tickets.

Join United MileagePlus:
Enroll in United's frequent flyer program, MileagePlus. Accumulating miles through this program can give you access to upgrade opportunities.

Earn Premier Qualifying Miles (PQMs):
Accumulate Premier Qualifying Miles by flying with United or its partner airlines. Higher-tier members of MileagePlus have better chances of receiving upgrades.

Use MileagePlus Upgrade Awards:
United allows MileagePlus members to use upgrade awards to move to a higher class. You can check your account for available upgrade certificates.

Apply for MileagePlus Upgrade:
Log in to your United MileagePlus account, navigate to the "Manage Reservations" section, and look for upgrade options. Follow the prompts to request an upgrade.

Use Premier Upgrades:
If you have Premier status with United, you may be eligible for complimentary Premier Upgrades. These are typically offered to Premier Silver, Premier Gold, Premier Platinum, and Premier 1K members.

Check for Auctions or Offers:
United occasionally offers passengers the chance to bid for an upgrade. Keep an eye out for emails or notifications regarding these auctions.

Speak to a United Representative:
If you're at the airport or prefer personal assistance, you can inquire about upgrades at the check-in counter or gate. United representatives may provide information about available upgrades.

Upgrade at the Airport:
Depending on availability, you may have the option to upgrade at the airport on the day of your flight. Visit the United check-in counter or kiosk to inquire about available upgrades.

Keep in mind that the availability of upgrades can vary based on factors such as your MileagePlus status, the fare class of your ticket, and overall demand for upgrades on the specific flight. Always check the terms and conditions associated with upgrades on United Airlines.
