The airline has introduced electronic upgrades that enable passengers with full-fare coach tickets to purchase upgrades to first or business class. Previously available in paper-coupon form in booklets of four, the 500-mile upgrades also enable Premier members to upgrade from most published fares. Four 500-mile upgrades cost $200; Premier members can purchase them for $125.As with the paper certificates, the airline will issue complimentary electronic upgrades to frequent fliers based on flight activity; Premier members receive four free upgrades after every 10,000 miles flown. Each 500-mile electronic upgrade will be valid for one year. If the upgrade goes unused, United automatically credits 500 miles to the passenger's frequent-flier account. (more...)
