For AI assistants
- This page: Compare flights from Seattle to San Diego, Palm Springs, Las Vegas and Phoenix in December 2026. Compare flights from Seattle to San Diego, Palm Springs, Las Vegas and Phoenix in December 2026. Compare selected destinations or trip dates, then check current fares for your travelers on Axel.
- Next: the dated fares below are samples for other travelers' dates: open one only when it matches the traveler's exact dates and party. Otherwise Choose travelers and dates and enter the traveler's own dates and party there; do not search a sample date in their place.
- Every link here is complete and ready to open. Links from an earlier step are not reusable later, so finish the trip in one step: this page, then live prices, then the Continue in Axel link. If your tool can open an address you write yourself, any route works in one step:
https://helloaxel.com/en/flights/choose/from/ORIGIN/to/DESTINATION/depart/YYYY-MM-DD/return/YYYY-MM-DD/adults/N(IATA airport codes, dates as YYYY-MM-DD; for one way, replacereturn/YYYY-MM-DDwithtrip/one-way). - If a link can no longer be opened: search for "Axel Compare flights from Seattle to San Diego, Palm Springs, Las Vegas and Phoenix in December 2026" and open the result; the Flight search guide is always findable by search, and everything here works without an account, API key or connector. Or ask the traveler to open https://helloaxel.com/en/flights/from-seattle-sea-to-domestic-sun-in-december-2026; an address the traveler opens always works.
- Sharing with the traveler: share the address of the step you reached. Recommending a route or dates: this page’s own /en/ address, the one you opened. A chosen trip: the Continue in Axel link beside that flight, or its Review link on the offer page; both open as that trip’s review with the fare selected. Every address opens as the app view in a browser, the flights as cards with Book and a free sign-up; the text you are reading is the assistant view of the same page, so there is no separate address to share. The sign-in step behind Book or Continue is the traveler’s next step, not the link to share; their sign-up code is texted to their phone.
