Attempting to Book YYZ-BKK-YYZ for fall 2007. The AC booking Engine for the return trip defaults to *A Code Share Flight BKK-NRT departing at 2355. I have selected a number of random dates in Decemeber and tried to "Book by Fare" and "Book by Schedule", in Lowest Economy, Flexible Economy or Executive First. Every option defaults to the same flight departing BKK at 2355. This means either a 9+hour connection time for AC2 to YYZ or 11+ hour connection time for Flight 4 to YVR.

I checked Travelocity.ca, Expedia.ca and Ticetpilot.ca and they all show *A flights BKK-NRT in the morning making legal connections to both AC2 and AC4. These sites also show *A flights BKK-HKG in the AM connecting to AC8 or AC16. The fares BTW are in the same price range as the AC.COM fares.

Why does the AC booking engine only show this single option to connect from BKK when there are several, more convenient flight connections available.
