No one likes to clutter up their inbox, but by signing up for mailing lists from airlines and search engines, you’ll be able to get updates about all the last-minute or special deals that are happening. This is one of the best ways to ensure you find a cheap flight. Why? Because they do all the work for you! Many times, the cheap flights are only available for 24 hours, and if you aren’t always checking the web for them, you will miss out on many of the super cheap deals. I would have missed out on a round-trip ticket to Japan for $700 USD (normally $1,500) or $500 flights to South Africa! Additionally, they offer frequent flier bonuses, and those deals have also gotten me free business-class tickets. These three websites are the best to stay on top of travel deals:

The biggest issue is that time spent in airports eats into the "free" time you would otherwise enjoy at your final destination. If you do settle for a trip with a long layover, check into sights to see or activities to do near your layover airport. A 10-hour layover might provide the perfect opportunity to visit a famous landmark or explore a new city. To each, his own.
By taking the two above mentioned approaches, you are sure to come across cheap airfare rates. Even if you can’t come across any amazing deals or discounts, you can still price compare airlines and specific flights to at least prevent yourself from paying more for your airline tickets than you need to.
If you want to travel to Europe during the summer (when, admittedly, everyone else wants to travel to Europe) you definitely can’t procrastinate. “Prices typically rise through the spring and peak in June as summer arrives,” Hopper’s data science team determined. And if you plan on traveling during a summer holiday — Memorial Day, the Fourth of July, Labor Day — the best fares can typically be found at least three weeks in advance of your departure.

Many of these budget airlines have their own airline rewards credit cards, and most of them offer a major signup points bonus. For example, the Southwest Rapid Rewards Plus card from Chase offers 40,000 points after spending just $1,000 in your first three months. However, a general travel rewards credit card such as the Chase Sapphire Preferred is the best option for most people, as you have the flexibility to redeem your points towards a wide variety of airlines and hotels. You'll receive 60,000 bonus points worth $750 through the Chase Ultimate Rewards program after you spend $4,000 in the first 3 months of your account opening, and the card features no foreign transaction fees.
