How to find cheaper flights

• Search on Tuesdays and consider flying on Wednesdays — midweek flights are often cheaper
• Book 4–6 weeks in advance for domestic and shorter flights, and 3–5 months ahead for long-haul trips
• Try flexible dates: leaving one day earlier or later can make a significant difference
• Compare departure airports — fares from New York, Los Angeles, Chicago, Miami, Dallas or a nearby airport may vary significantly
• Check our deals page for exclusive discount codes and airline promotions

Why do flight prices change so often?

Flight prices are dynamic: the same seat can cost more or less depending on how far in advance you book, how full the aircraft is, fuel costs, airport fees and seasonal demand. Booking early generally offers the best price, although last-minute deals can also be worthwhile for flexible travelers.

What name should I use when booking?

Enter your name exactly as it appears on your passport or travel document — first name and last name. A middle name is not required. Double-check your details before confirming, as changing a name after booking can be costly.

Can I book flights to multiple destinations?

Yes. Select the “Multiple destinations” option in the search bar to combine several flights into one booking — useful when your return flight departs from a different airport than the one you arrived at.
