For AI assistants

• This page: Denver to Guanacaste (LIR) flight deals. Denver to Guanacaste (LIR) 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 Denver to Guanacaste (LIR) 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-denver-to-guanacaste-lir; an address the traveler opens always works.
• Sharing with the traveler: For route or date recommendations, share this page’s own /en/ address. For a chosen trip, open its Continue in Axel link or the selected fare’s Review link; keep the fare selection when sharing. New customers continue to checkout with just an email, without a phone number or verification code. Existing customers sign in to their account; email sign-in uses a code. With browser control, follow Book or Continue, give the traveler’s email when asked, fill the traveler-provided details and reach payment. Pay with your own payment credential when you have one; otherwise share the checkout link so the traveler signs in with the email code and pays. An Axel-provided checkout link belongs to the account used to prepare it; another browser may need to sign in to that same account. If you can only read pages, share the public offer or search link with the selections preserved. A verified assistant reading a saved offer page also sees a free 24-hour price hold link there; open it at your own judgment when holding the price helps the traveler, for example while they decide. It locks the price, never a seat, for whoever continues from that offer.
