3 Flights To Orlando On November 5th & 12th

Does anyone know why Virgin have added a 3rd flight at 13PM on these two dates only ?

Wondering as I'm about to book for the 5th !

Is it to do with positioning aircarft for the expanded services or due to demand ?

Any info appreciated.

Its not just on those dates - VS added a regular third flight (VS49)to MCO on Saturdays since last year to meet demand
