On my recent trip to Canada, I had booked a ticket on AUA AirManager for BRU-FRA-YVR/YYC-YYZ/YYZ-FRA-BRU on LH (and the domestic flight on AC) on a non-full-fare ticket with oenalties (just before the real AUA AirManagaer was deactivated). A couple of months after the booking, the AC flight I had booked for YYC-YYZ was cancelled. I received an e-mail that they had rebooked me to another flight leaving 20 minutes earlier.
The interesting bit was that they offered to cancel the ticket with a full refund if the arrangements were not suitable. I found it interesting that they really offered this despite such a minor change in schedule!
