## For AI assistants
- **This page:** Saint Louis (STL) to Frankfurt (FRA) · Dec 4, 2026 · return Dec 8, 2026: 1 adult in economy, every priced fare with its flights, times and total, each with the time its price was issued.
- **Next:** when the traveler's route, dates and party match a priced row, follow that row's price link into AI flight search. Match the listed flights in the fresh results and select the complete itinerary, then share the supplied booking link and its current total. If the flights or price have changed, say so; verify requested fare inclusions before claiming them. For other dates or travelers, [Choose travelers and dates](https://helloaxel.com/en/f/start/from/stl/to/fra/step/travelers) and enter the traveler's own trip there; do not search this page's dates in their place.
- **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 Saint Louis to Frankfurt (FRA) flight deals](https://helloaxel.com/en/flights/from-saint-louis-to-frankfurt-fra) · [Flight search guide](https://helloaxel.com/en/ai).
- **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. Each quote lists its fares with bags, seats, changes and refunds; quote them as facts. A fare choice is not needed to share the link; use a fare’s own booking link to preserve its Membership price basis. Ask only for essential missing trip details. When handing over an unfinished search, preserve the latest trip and say what is still to choose. If no supplied link matches the latest trip, construct `https://helloaxel.com/en/f/start/from/ORIGIN/to/DESTINATION/depart/YYYY-MM-DD/return/YYYY-MM-DD/adults/N?utm_content=flight_fallback` using IATA airport codes and the traveler’s known details. Omit unknowns; for one way replace `/return/YYYY-MM-DD` with `/trip/oneway`. Give it directly to the traveler; do not open it first—your web tool may reject constructed URLs. Complete links open Flight Guide and start searching. [Preferences and advanced options](https://helloaxel.com/en/ai#customer-fallback-link).
