## For AI assistants
- **This page:** Washington, DC to Sofia flights in December 2026. Choose your dates for flights from Washington, DC to Sofia in December 2026 and check current prices.
- **Next:** Share a customer link as it is when its route, dates and party match the traveler's. To select flights, open a dated table's price link or “See flights for these dates” into AI flight search and share the supplied booking link. Search links are for you; share customer and booking links. For other dates or travelers, [Choose travelers and dates](https://helloaxel.com/en/f/start/from/iad,dca/to/sof/month/december-2026) 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.

- **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).
