One-way pricing is the part of air travel that behaves least intuitively — on many carriers a single leg costs more than half a roundtrip, and on some it costs nearly as much as the full return. That makes comparison shopping disproportionately valuable on one-ways, which is exactly what an aggregator does. Code OW40 applies up to $40 off one-way bookings at CheapOair through 6 September. The use cases are specific: relocations, students heading to campus, open-jaw trips where you are returning from a different city, and anyone flying out with no fixed return. Compare across carriers before booking, since the spread on one-ways is wider than on returns.
