How to Find cheap holiday if you have Annual leave booked and no plans and flexible on destination?
I only recently discovered that on sky scanner if you insert you local airport as the "From" location (and if you live in london put down london(Any)) and put down "Everywhere" as your destination you will get a list of multiple destinations for flights that suit your dates sorted in price order.
If you click on these the website takes you to the relevant carrier.http://skyscanner.com
Have saved a fortune recently and seen much of europe on a tight budget! with several destinations listed at <£40 return
Hope that helps anyone out there!
