Just another one to confirm...
I booked a trip from IAD up to YUL in February last year on Travelocity with their 'Last Minute Packages'.
I was able to do everything just as if it was a 'normal' UA ticket purchase - Elite Checkin/RCC Access (as *G)/Priority Bags (which actually worked in YUL)/E+ Seating on E70/MLL Access (Much better than Domestic RCC of course) and you got it...MP Miles, both EQMs and RDMs (with bonus).
Not bad for a shade more than $300, staying in the Hyatt in downtown Montreal too
So book, be happy and have a nice trip!
