Do I get UA MileagePlus Miles flying on AC1853 (Air Canada Rouge flight). It seems it won't allow me to enter on line my wife's MileagePlus number. After I enter the update says Error 68003 - contact air canada reservation (where there's a one hour wait time).
My UA MileagePlus number is linked though to the booking since I made the booking. My wife's hasn't been linked though. Neither then nor that I can do it now.
Thank you
