FlyerTalk Forums - Buy up to higher fare class w/o change fee? {GG BUYUP}

"GG BUYUP" references to a policy (not publicly published) that UA will waive change fees, if on your presently booked flight you wish to buy-up / upfare to the next cabin. That is, pay the fare difference from your present economy fare to business / first.

If the agent is unfamiliar with the policy, ask them to reference "GG BUYUP" or ask a supervisor.

Note this is only on UA tickets and only applies to the same flight, flight changes are not permitted by policy (a rare agent might but generally no).

This does not waive change fees for buying-up to a "W" fare to apply a GPU but some agents may still waive the change fee and some may not.
