I think getting good flights/holidays to Florida is all about being in the right place at the right time!
We always have to go at peak times - due to kids in school and DH being a college lecturer, so we know what it's like to pay peak prices!
Next summer we wanted a flight, car and villa for just three of us! I managed to get Virgin flights through opodo at £640 each (£850 everywhere else), and have shopped around for a villa to suit us etc.. In total for three of us in high summer it has cost less than £3,000. To book the same holiday, direct with any travel company works out hundreds, if not thousands more!!
Saying that, I did a search for flights last night, and the cheapest with opodo now, for the same time next year, have gone up to £750 - and that was with Iberia - a 32 hour flight to orlando!!
Am I glad I got those Virgin flights when I did!!
It pays to keep looking, and doing like for like quotes, so you know exactly what you're getting!
