How to use AI to book cheap flights
Why conversational AI finds better fares than filter-heavy search engines — and how FlyAgent's Jack does it live.

Why traditional flight search leaves money on the table
Metasearch sites are optimised for one query at a time: pick an origin, a destination, an exact date, click. They hide the two levers that actually move price — date flexibility and fare-family trade-offs — behind extra clicks and separate screens. Most travellers never touch them.
What an AI flight assistant does differently
- Parses intent, not fields. "Frankfurt to Lisbon next weekend, carry-on only, flexible on the return" becomes a live multi-date, multi-fare search instantly.
- Ranks trade-offs. Instead of a wall of results, an AI concierge explains why option A is €40 cheaper than B, or why leaving one day earlier saves €120.
- Handles fare families in plain language. "What changes if I want a checked bag?" is answered in the same chat, without re-searching.
- Books, doesn't just search. The best AI flight booking assistants issue real tickets via a certified GDS — not affiliate redirects.
A practical workflow for finding cheap flights with AI
- Describe the trip, not the search. Include origin, destination, a rough window, who's flying, and any deal-breakers (max stops, cabin, bags).
- Say what you're flexible on. "±2 days either side," "any nearby airport," or "cheapest week in May" typically unlocks 15–30% savings.
- Ask for the trade-off. "Show me the cheapest with one checked bag included" is faster than filtering.
- Let the AI reprice at booking. Fares move. A good AI concierge re-checks and flags any change before you pay.
