Just the YYZ-JFK leg (and back). They had the rights to sell this (in 1997 I think) and it was way cheaper than flying AC or whoever.

In one direction they were running a 767. There was a strike that hit mainline services (think it was cabin crew) so they ran the bigger plane out of the regions.

Don't remember the loads being very good, but bizarre to get the worcestershire sauce pretzel things with a G&T on a short hop in N. America.
