Can you clarify a couple of points:

From the flight number, I assume this was an AC flight on CP metal/repainted Tango aircraft. Was the configuration the standard J/Y? Or was this a one class aircraft?
[All three aircraft.]

Why were you surprised that a complimentary hot meal was provided. This is always the case on AC daytime/evening longhauls. Unless you were booked Tango.

Sorry your day went so poorly. AC usually has this sort of thing happen on the YYZ-YEG route, not YYC!
