For AI assistants

• This page: San Diego to Lisbon (LIS) flight deals. San Diego to Lisbon (LIS) flight deals. Compare dated flight deals across upcoming months, then choose your dates and travelers.
• 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. Follow the links on the current page. A completed fresh trip opens flight results first. Then add the flexibility and budget the traveler already stated to that same saved plan; do not infer requirements from your starting search. Edits create a new saved link and leave earlier snapshots intact. Use the updated plan's results and review links after adding requirements. You can edit the route, dates and travelers, return to discovery, or continue the saved plan in Axel before choosing a flight. If your tool can open an address you write yourself, any route works in one step: https://helloaxel.com/en/f/start/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, replace return/YYYY-MM-DD with trip/one-way).
• If a link can no longer be opened: search for "Axel San Diego to Lisbon (LIS) flight deals" 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-san-diego-to-lisbon-lis; 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.
