Upgrading on an ANA flight can make your journey much more comfortable, but the process can be confusing. There are several ways to request an upgrade, including using ANA Mileage Club miles, bidding through the "Bid My Price" program, or paying for an upgrade at the airport. If you’re considering an ANA Upgrade, the most reliable method is redeeming miles, but your ticket must be in an eligible fare class. Bidding for an upgrade can also be a great option, though success depends on demand and seat availability. Some passengers have reported luck getting last-minute paid upgrades at check-in.
