Add an extra destination after Seattle

A multicity ticket, Seoul to Seattle plus a later journey to or from a third city, sometimes prices below the plain one-way. You fly to Seattle; the second journey is a spare multicity you are free to drop, reschedule, or fit into a later trip. As with a spare return, the spare part is a whole journey on a later date, so nothing is skipped on the day and you can check a bag.

Book a SEL-SEA roundtrip that costs less

Airlines often price the Seoul to Seattle round-trip below the one-way, so you buy the pair and never fly the return. That is a spare return, a form of throwaway ticketing, and nothing is skipped mid-ticket: your checked bag and your outbound are unaffected. When the fare allows it, you can also reschedule or cancel the extra return.

Fly to a cheaper city and stop in Seattle

A ticket to a city beyond Seattle, routed through it, sometimes costs less than the Seattle ticket itself. You get off at the layover and skip the last flight, a hidden city (or skiplagging). It is the one method here that leaves part of the ticket unflown, so travel with a carry-on, and it cannot be used on a round-trip: a missed segment cancels everything after it. Airlines tend to curb this practice, avoid doing it too often.

Return to another city and stop in Seoul

Instead of the Seoul to Seattle round-trip, you book one multicity ticket: Seoul to Seattle, then Seattle to a third city with a stop in Seoul, where you get off and skip the last flight. That hidden return gives you the same round-trip for less. As with a hidden city, a segment goes unflown: travel with a carry-on, and avoid doing it too often.

Combine your trip with other upcoming flights

If you have other trips coming up, try combining them with the Seattle one. Our multisearch engine searches several trips at once and finds ticket arrangements that cost less than the sum of their parts, such as nested or back-to-back tickets. The other trip can be to Seattle again or somewhere else entirely, and it can be months away.

Questions about saving on flights to Seattle

Can I buy a round-trip to Seattle and not fly the return?

Yes, that is a spare return: nothing on the ticket is cancelled, you simply forfeit the return. On this route the round-trip priced below the one-way on a minority of searches, saving 15–20%.

Is a hidden-city ticket safe on flights to Seattle?

Safe enough with two rules: carry-on only, since a checked bag travels to the ticketed destination, and not too often, since airlines curb it. On this route a hidden city ticket routed through Seattle priced below the Seattle fare on a good share of searches, saving 5–30%.

Can I use a hidden-city ticket on a round trip to Seattle?

Not on a plain round-trip: skipping a segment cancels everything after it, so you would lose the return. What works is a hidden return, one multicity ticket from Seoul to Seattle and then from Seattle to a third city routed through Seoul, where you get off. On this route it beat the round-trip fare on a minority of searches, saving about 5%.

Is an open-jaw ticket cheaper than a one-way to Seattle?

Sometimes. A multicity ticket with a later journey to or from a third city, a spare multicity, can price below the plain one-way, and since the unused journey is on its own date you can check a bag. On this route it did on a minority of searches, saving 5–10%.
