Shannon, I've a question for you.
I have never had a CO OnePass account. So, all my currently booked future travel has my UA MileagePlus number.
I know that going forward the OnePass style alpha-numeric frequent flier numbers will be used. I know from your previous posting that our legacy 11 digit MileagePlus numbers will continue to be valid "for some time."
The question is, do I have to call to convert all my future travel itineraries to my new alphanumeric MileagePlus number? Or will that be done automatically?
Thanks!
