How this service works
KAYAK flight route overview between two city or airport codes (e.g. LON to PAR): up to 20 recent round-trip deals KAYAK found (airline, departure/arrival airport, departure time, duration, price in USD), the route's lowest recent price and KAYAK's published route insights as question/answer text (typical price range, cheapest month, day and airline, delays, flights per week). From KAYAK's public route page; not a live date search.
Output
A JSON response containing up to 20 recent round-trip flight deals (airline, departure/arrival airports, departure time, duration, price in USD), the route's lowest recent price, and KAYAK route insight Q&A covering typical price range, cheapest month, cheapest day, cheapest airline, delay patterns, and weekly flight frequency.
Example use cases
Budget trip planning research
“I'm thinking about flying from New York to Miami — can you pull up KAYAK's route overview for NYC to MIA, including the cheapest month to fly and what round-trip deals have been available recently?”
Comparing route costs before booking
“Before I commit to a flight, can you check KAYAK's route page for San Francisco to Tokyo — I want to know the lowest price they've seen, how many flights per week there are, and which airline tends to be cheapest on the SFO to TYO route?”
Travel agent briefing on route trends
“Give me KAYAK's route insights for Dubai to Singapore — DXB to SIN — including typical price range, which day is cheapest to fly, and any delay information they publish.”

Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/travel/kayak?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-date-required overview of typical fares, airline options, and route trends between two cities or airports. It is ideal for research, budgeting, and travel planning contexts where the user wants historical pricing patterns and route insights rather than live booking availability for a specific date. Not suitable when you need real-time seat availability or a specific travel date search.
Side effects
- Invalid or unrecognized IATA codes return an error or empty results
- Route with no KAYAK data returns empty deals array
- Insights may be absent for low-traffic or obscure routes
- Data reflects KAYAK's cached route page, not live availability — prices may be stale
- Missing required 'from' or 'to' parameters returns a validation error
