3 Holiday Travel Hacks That Frequent Fliers Don't Even Know

Flying isn't exactly a stress-free experience, especially around the holidays. In an effort to make your holiday travel experience as painless as possible, Insider recently compiled a list of travel hacks that go beyond "bring a water bottle" and "pack light." Designed to alleviate stress for even the most frequent of flyers, the following three hacks will truly change the way you travel:

Sign up for TSA PreCheck or Global Entry: Dubbed "express lanes for the proactive" by Insider, TSA PreCheck ($85) and Global Entry ($100) preapprove you as a low-risk traveler with the U.S. Customs department. This means you can cut the long security lines for domestic travel and skip some time-consuming paperwork when returning home after international travel.

Book two one-way flights: Believe it or not, booking two one-way flights through two different airlines can be cheaper than a round-trip flight. "Plus, it may get you better arrival and departure times as you can mix and match flights," explains Insider. The site recommend checking booking sites like Kayak or perusing the airline websites directly for even better discounts.

Book non-U.S. airlines if possible: While this option isn't always available, foreign airlines offer more in the way of in-flight amenities, including hot towels, pillows, blankets, food, and drinks.
