How does KAYAK find flight deals under $100?

KAYAK aggregates deals from hundreds of travel providers to allow you to quickly and easily compare flight deals from United States that match your budget. Utilize the available filters to narrow down deals to those that are perfect for you.

Is it easier to find one-way or round-trip flight deals under $100?

Getting a flight under $100, either one-way or round-trip, can hinge on a few things like your destination, the airline you choose, and when you're buying the tickets. Round-trip tickets used to be the standard, but these days, with budget airlines and more competition, that's not always the best option. For domestic flights or short trips, you might find a better deal by looking for one-way tickets under $100. This is especially true if you're flying with a budget-friendly airline. If you're heading overseas or on a longer journey, round-trip tickets under $100 usually provide more value. Another savvy way to stick to a $100 budget is by booking two one-way tickets with two different airlines. This clever strategy is known as a "hacker fare".

Are flights under $100 available with popular airlines?

Yes – deals on flights under $100 can often be found on KAYAK from popular airlines such as Avelo Airlines, Contour and Southern / Mokulele. Deal availability does depend on several factors including the specific flight route you’re interested in, departure dates, and booking period. Be sure to check back regularly as new deals are often being discovered by KAYAK users.

Are there deals on flights under $100 to domestic destinations?

Yes – KAYAK often has deals on flights under $100 departing and arriving within United States. Deals may vary depending on your preferred origin and arrival airports, as well as the time of week and year, so be sure to check back soon if you’re not finding the flight deals you’re looking for.

Are there deals on flights under $100 to international destinations?

Yes – deals on flights under $100 arriving outside of United States can often be found on KAYAK. As international travel can often cost a bit more than domestic, the types of flight deals may vary (one-way or round-trip) depending on the flight route and time of year you’re looking to travel. Be sure to check back soon if you’re not finding the right international flight deal under your budget as deals are consistently being refreshed.
