After a few failed attempts to put our United Mileage Plus miles to use, we were pleased to discover that we can transfer them over to Continental OnePass to our benefit. Yes, miles are now transferable among OnePass and Mileage Plus accounts, so shift 'em around however needed (for award tickets, non-ticket rewards, or a little extra push to a higher elite status) until next year rolls around, when the two programs combine into one.
When transferring miles, just remember:
Miles can be transferred once a day, in increments of 1,000, with a limit of 200,000 per transfer.
You can transfer miles only between accounts in your name.
Change your mind? You have 24 hours to return miles to their original account. Transferring miles will not affect your elite status in either program.
