Book any flight. Earn Dyme Miles on every dollar.

For US domestic trips, fares are usually lowest about three to seven weeks before departure. For international trips, look one to three months ahead, and earlier for peak times like summer in Europe. Very last-minute fares are rarely the cheapest.

Usually round-trip. Within the US, a 2025 analysis found two one-way tickets cost more than the round-trip on over half the routes checked, and on over 90% of them within two weeks of departure. International round-trips are almost always cheaper than two one-ways. Two one-ways can still win when you mix airlines or fly home from a different city, but they are separate tickets: if the first flight is late and you miss the second, the airline doesn't have to rebook you.

Connecting flights are often cheaper than nonstops on the same route. Red-eyes and early-morning flights sometimes are too, but it varies by route, so compare them when your times are flexible.

Four things make the biggest difference. Fly midweek: Tuesday and Wednesday departures are often the cheapest, and in Expedia's 2026 data US domestic flights leaving on a Tuesday averaged 14% less than those leaving on a Sunday. Avoid peak dates like holidays, school breaks and big local events. Book in the right window, about three to seven weeks ahead for domestic trips. And check a day or two either side of your dates, and nearby airports, before you book.

Yes. Every dollar earns one Dyme Mile, on top of any airline miles or credit-card points you already collect. You can use Miles on any flight or hotel on Dyme, with no blackout dates.
