Cheap One-Way Flights
On most US domestic routes, a one-way fare is priced at roughly half the round-trip, which means two one-ways — even on two different airlines — often cost about the same as a single round-trip while giving you far more freedom. That is the opposite of international travel, where a one-way can cost nearly as much as a return, so the strategy is route-dependent.
One-ways are the right tool for open-ended trips, for booking the outbound now and the return once plans firm up, and for catching the cheapest carrier in each direction rather than being locked to one airline both ways. They also make an open-jaw trip — fly into one city, home from another — simple to build.
The routes below have the lowest one-way fares on record. Pairing two of them, or mixing a one-way with a flexible return, is worth pricing against the round-trip before you book.
These are recorded lows, not live quotes. Call and an agent will price the one-way and the round-trip side by side so you take whichever is genuinely cheaper for your dates.

Making one-ways work for you
- On US routes a one-way is usually about half the round trip, so mixing airlines for the outbound and return can beat a single round-trip ticket.
- Two one-ways do not protect each other — a delay on the first is not the second airline's problem, so leave room between separate tickets.
- International one-ways are often priced near the full round trip; there, one ticket usually wins.
- Checked bags do not transfer between separate tickets; you collect and re-check them.

Frequently asked questions
Is a one-way ticket more expensive?
On US domestic routes, rarely — one-ways are about half the round trip. On many international routes a one-way can cost nearly as much as a round trip, so ask an agent to compare.
Can I mix two airlines for the outbound and return?
Yes. An agent can book the cheap morning departure on one carrier and the cheap evening return on another as two one-ways when that is cheaper.
Will a one-way cause problems at immigration?
Some countries ask for proof of onward travel. An agent flags this for your destination before you book.
Are these fares live?
No. They are the lowest fares recorded recently on each route from cached search data, refreshed nightly. The agent quotes the live price when you call.
How do I get one of these fares?
Call (708) 866-8751 with the route and your dates. If the recorded fare is still available the agent books it; if not, they find the closest current fare across all airlines.
Can I book these online?
No. Every booking is made by phone with a licensed agent so names, dates, and fare rules are confirmed before payment.
