If you would only know what their business looks like..
Sample dates 11/29-12/20search on google flights - it will show $1944 than choose cheapoair the price should go down to $1800
Anything for the end of December?
I'd rather do DL from YYZ for the same price (very limited dates last I checked). Loads of SkyTeam dates available, but not NS.
even cheaper, and better if you stay in NY and dump the last leg
When traveling with kids, I'd much sooner fly Y direct than J with a stop (unless I can tour the stop over city)
Sample?
Of course the journey starts in YYZ, but you can just leave the last portion
