Try to catch a flight on Wednesdays.
Wednesdays are historically the cheapest day to fly of the week. By doing this you can cut your cost of the ticket by half. There will also be fewer people on the flight making this a win win for everyone.
Buy one at a time.
Do not purchase tickets as a group because even if there are cheaper seats on the plane you are going to end up paying the same price for every seat. Instead buy one ticket at a time. Who cares if you are sitting next to each other or not right?
Look for alternative routes.
Looking for alternative routes will save you money because most people choose the most common route making it popular and expensive. Instead check if there are flights with connections to find a cheaper flight.
Try to work with the weekend for a round-trip flight.
This has the same concept as the Wednesday flights. If your flight takes off on Friday you can bet that you will pay a bit more than if your flight leaves on a Saturday night instead.
Try to do some research and see if there are any airports that are close enough to where you are going to drive to. By doing this you might be able to cash in on a much cheaper flight.
Check to see if there are smaller airports. Some of the smaller airports do land jets and if you fly to them it may be a bit cheaper.
Do some research online
With competition now days it can be very hard to find the right price you are looking for. So make sure you go online and do some price comparisons first before buying that ticket. Some good websites you can try are Kayak, Hotwire, Best Travel and Cheapoa
Book a red eye flight.
Red eye flights are by far the cheapest, probably because no one likes to fly overnight but if you are on a budget and you are able to sleep on the airplane then this is the way to go.
