I'm flying from Toronto to Taipei, December 13, on a paid business P fare. The current routing is YYZ–ICN–TPE on AC 061 and AC 6534 (EVA). Is it possible to do a same-day change to YYZ–HKG–TPE on AC 015 and CX 472 or BR 856? I'm interested in getting into Taipei a bit earlier.
The non-AC operated segments make me unsure if this is possible or not. AC 017 (YVR–TPE) isn't flying that day, so there isn't an all Air Canada metal option.
I read through some past threads about same-day changes and codeshares (
1,
2,
3,
4), but there isn't a clear answer to me. Any thoughts or experiences?
