I went into the United ticket office near here Thursday, and tried to move my flight to Melbourne up to August 31 (or anywhere that week), but there are no award seats left. Ended up cancelling entirely, and will just plan on coming over next year (would be my 9th trip over, so I can skip a year). Wanted to drop this from a 5 week trip down to a 3 week trip, but just didn't work out.
