Made a reservation (actually 2) on the 19th for Air Canada YEG-YYJ-YYZ-DXB using united miles from each of my wife's and my accounts. Everything seemed fine and all previous bookings with UA miles for Air Canada have been ticketed pretty much right away, but now 2 days later and reservation has not ticketed. We have the Air Canada PNRs and payment is pending on the credit card, but United has redeposited the miles into our accounts, showing on the 19th, same day as they were booked. Anybody seen this before?
