Not only does it help to be flexible with dates and destinations but being flexible with the route you take is another way to get a cheap flight. Sometimes it’s cheaper to fly to London and take a budget airline to Amsterdam than to fly direct to Amsterdam. There are so many budget carriers around the world that taking advantage of a good deal to another city and then hopping on a budget flight to your destination is sometimes the best way to go. I had to go to Paris once; the flight was $900 USD, but I could fly to Dublin for $600 and get a $60 flight to Paris. It meant more flying time, but the $240 I saved was worth it.

Depending on where you want to fly to in the USA will depend on the peak seasons. Due to the many, many states it can be hard to pinpoint exact months of the year to visit. Atlanta and Miami for example see the peak season from March to May and September to November. Las Vegas on the other hand is busy almost all year. You’ll find cheap flights to the USA if you go to Vegas during the Summer as temperatures in Las Vegas can get ridiculously hot. Once you’ve decided on a location in the USA you can start researching the peak seasons for that state or city and then secure cheap flights to the USA.
