Having some flexibility with your dates of travel is one factor when it comes to finding cheap overseas flights. Booking at least several months ahead of time can also help to save money on airfare, as can traveling during the week instead of over the weekend. And it’s also worth comparing the airfare into different airports; flights to London may be less expensive than the ticket price to Paris or Brussels and from London it’s easy to get to either city inexpensively. Check with the low cost airlines that have sprung up all over the world; these often don’t appear on flight searches meaning you have to check their individual website. And don’t forget to ask for any discount that might lower the cost of your plane ticket, such as senior, military, frequent flyer or a group which is often considered 10 or more people.
