I've just booked next year's holiday, 2 weeks in Florida for 5 of us.
I was looking at the Virgin website, the resort I wanted for our chosen dates was almost 9k.
So I have shopped around and played with chopping up the flights and have managed to get the same holiday (actually upgraded the accommodation) for £3200.
We have to change planes in Montreal and it's 13 hours travel time instead of 9 but for a saving of nearly 6k, I can live with that.
Crazy price difference. I've never bothered doing this before because we've never done long haul as a family but I always will now!
