TCX Summer 16
So looking at the TC booking site it appears Orlando is Daily starting July14th through to September 10th with 2 flights available on Mondays, Fridays and Sundays.
Cancun weekly on Saturdays and Las Vegas on Thursdays.
does suggest they will have two wide bodies based at the airport plus three A321s.
With the TOM 787 mentioned above that's a pretty decent long haul offering. I hope the terminal can cope
