Since you don’t know exactly when these changes are going to happen, it is important to check often at least every day, preferably several times a day. You may be lucky enough to come across cheap fares.
Some sites allow you to set alerts for specific routes. Others are set up to let you track specific flights. The approach may be to set a particular price you want to pay, and when the route or flight drops to (or below) that number, you receive an email. Know that because the fares change so often, it’s important to book quickly when an alert arrives if you like the price. If you wait, the fare could be a lot higher by the time you are ready to book.
Try off-peak and off-hours
This is very simple: lower demand means lower prices. As such, make efforts to find out the off-peak as well as off-hours period for your route so that that you can take advantage of the lower prices.
You should visit several websites to view and compare prices before settling for the cheapest one. If you simply accept to book the fare of your favourite booking website, you may be paying more than the usual price.
This is the most important secret for anyone who is looking for a cheap flight. This is because airlines increase their fares as the flight date gets closer.
