ne of the questions I'm asked the most frequently is, "How do you find those low airfares?"
Unfortunately, there isn't an easy answer. There's no one magical way to always get the cheapest airfare every time. It takes a lot of time and effort, and there are no guarantees. Being flexible is really a must, as the cost can vary by hundreds of dollars from one day to the next. Usually, if you can avoid traveling on a Friday, Sunday or Monday, you'll get a better rate, but that's not always the case. And, if you have your heart set on flying around a major holiday, don't expect bargain prices (the exception is flying internationally over the Thanksgiving holiday, a time when airfares can be very low).
Check Google Flights
It's important to compare fares on a few third-party booking engines like Expedia or Travelocity, but one of the best places to start these days is on Google. Google Flights will let you pull up a calendar so you can choose the date with the lowest airfare, and it tends to be very reliable too. While you can't book it directly there, it will tell you where you can. You may want to check directly on the airline site as well.
Sign Up For Alerts
Many travel web sites offer to email airfare alerts, letting you know when an airfare goes below a certain price. Google Flights is one of them, but you may want to sign up for a few as they all work differently.
Low Cost U.S. to Europe Airlines
If you want to go to Europe, there are now two low-cost carriers flying between the U.S. and many locations throughout Europe, including Norwegian Air and Wow Air. Wow Air is based in Iceland, and it also offers the chance to spend a layover in Iceland without any extra cost. You will have to pay extra for baggage fees and other services, but most of the time, you'll still save big. Norwegian is very bare bones, but I paid just $149 for a one-way airfare from London to JFK recently.
Timing Your Purchase Right
Timing your airline ticket purchase right is essential, as rates change daily, and sometimes even hourly. Certain trends can help to increase your chances of getting the lowest airfare; the best deals are usually found between Tuesday and Thursday, while purchasing 11 to 12 weeks ahead of your anticipated travel dates is also considered optimal. As that's not always the case, your best bet is to check frequently - every day, and even more often, at various times of the day, if you're able.
