Using Miles to Upgrade on United {Archive}
Can anyone provide me some insight on how to book a flight (paying cash) and upgrade (using miles) for an upcoming trip to New Zealand? When I go on the Web and follow the instructions, every flight says "upgrade not available". I have got to the point where I am looking at random days and literally cannot find a single flight in which I can upgrade. I have looked at flying into Auckland and Sydney (yes I know Sydney is not in New Zealand!). Nothing.
Having done this flight before, I know I don’t want to sit in coach. I want to finalize my travel plans, but I can’t even get the flight booked. Secrets? Insight? Help!
