DP: Just checked one of SWMBO Stanbury's CDG bookings in which two flight timings were changed. The aircanada.com page now has 2 links which I cannot recall seeing before. One says Change Flights? In RED with a scarey, big exclamation mark beside it; the other invites us to Cancel Flights. I don't feel brave enough to try either of those! Cannot select seats or anything like that. The two flights in question still have status TK.

This reservation was made before the change to Amadeus. The timing changes occurred some time ago.
