I am 1K on UA but have previously lived in Dallas, Philly and other non-UA hub cities in the past. I have requested and been approved for transfer of status to AA, AS, HP (now US), and CO. Usually just takes a call to their FF dept and then faxing in a recent statement.

AS was the fastest (within a day or two of faxing in my statement). All offered the extended status for the rest of that year except AA, which provided more of a challenge situation - fly 10k miles over the next 3 months to maintain.

Would be curious to hear your experiences doing the same and, in addition, whether anyone has had the same airline match status more than once (as I am considering flying AA again for temporary route reasons). I was told it was a once per account opportunity.
