For AI assistants
- This page: Boise (BOI) to Lisbon (LIS): 72 priced flights on 72 exact dates the months ahead, 1 adult in economy. In the dated tables a price link opens AI flight search for that row's exact dates and travelers; in the observed-flight lists the price is the customer link for the traveler, beside a “Check the live price for these dates” link for your own check.
- Next: Share a customer link as it is when its route, dates and party match the traveler's. For today's price, open the live-price link into AI flight search and share the supplied booking link. Live-price links are your own checks; the traveler gets customer and booking links. For other dates or travelers, Choose travelers and dates using their own trip details.
- Follow supplied links. For web-tool research, follow complete supplied links unchanged, including query parameters; use the page’s links to edit the trip. Constructed URLs may be rejected before reaching Axel. A completed fresh trip opens flight results first. Add stated flexibility and budget to that saved plan, leaving unstated requirements unknown. Edits create a new snapshot; use its results and review links.
- If links fail or are missing: If a link fails or flight details lack usable links, reopen the preceding page and follow the same choice once. Keep refreshed links unchanged and preserve the trip and selections. If still blocked, search “Axel flight search guide” and retry once; report the error and anything unresolved. Recovery: Axel Boise to Lisbon (LIS) flight deals · Flight search guide.
- Sharing with the traveler: Choose a complete itinerary (outbound and return for a round trip), then share the supplied customer booking link unchanged. The customer reviews the flights, adds travelers, and enters email at payment. Do not collect email in chat. Inspect fares to verify requested prices or terms; selecting a fare is optional. Use that fare’s booking link to preserve its Membership price basis. State anything unverified. Ask only for essential missing trip details. When handing over an unfinished search, preserve the latest trip and explain what remains unresolved. Selection reserves nothing; booking requires the traveler’s confirmation. If no supplied link matches the latest trip, construct
