I just had an AE ticket with some TK segments have a schedule change. 1 of the 4 legs now departs and arrives 30 minutes later. No big deal. Everything else, including all flight numbers and aircraft types remain exactly the same.

I go to the Aeroplan website and I can't even view the details of the booking. AC website is showing duplicate legs. Everything looks perfect on the TK site, showing the new times with the old ticket numbers.

Having heard this song before, I call Aeroplan, who says I can't view the booking because of a schedule change, and agent goes to clean up the file. To her credit, she did so right away, new e-mails received within a minute, and all looks well again. And, I was connected to an agent within 30 seconds of punching in my Aeroplan number.

However, why do they have this need to issue a new ticket number for something as simple as a 30-minute schedule change? Annoying, but I have to go back and reselect seats as a result. But, it worries me about what could have happened if I hadn't been checking my bookings regularly. Would the TK flights have been dropped while the booking sat in the limbo status?
