Travel the Day Before or During the Holidays
If your travel plans are flexible, consider playing around with your travel dates to take a little stress off you and your wallet. Breffni Horgan, head of product and design at Hostelworld, explains that airports are often less crowded the day before or the day of major holidays. So not only will wait times be substantially shorter, you can also typically score a much cheaper flight.
She also encourages travelers to take advantage of apps that track prices. "If you want to find the cheapest time to fly, apps like Skyscanner and Hopper can track prices for you and alert you when the destination drops in price, doing all the work for you!"
