Each item in `itineraries` has:\n- `price` (number) and `priceFormatted` (e.g. \"123 EUR\")\n- `totalDurationSeconds`\n- `bookingUrl` — the link to book the flight\n- `imageId` — destination city id for a hero photo (https://images.kiwi.com/photos/600x600/{imageId}.jpg)\n- `baggage` — total included baggage across all travelers: `{ personalItem, cabinBag, checkedBag }` (counts)\n- `outbound` (and `inbound` for return flights), each a leg with: `route` (list of airport codes including layovers, e.g. [\"PRG\",\"MAD\",\"BCN\"]), `departureTime` / `arrivalTime` (local ISO timestamps), `durationSeconds`, `stops`, `cabinClass`, and a `segments` list. Each segment has `from`/`to` (IATA), `fromCity`/`toCity`, `fromName`/`toName` (full airport names), `fromCountry`/`toCountry`, `carrier` (code) and `carrierName` (airline name), `flightNumber`, and `cabinClass`.\n\n## How to display\n\nRender a markdown table. Group results into cheapest (lowest `price`), shortest (lowest `totalDurationSeconds`), and other notable options. For each itinerary show, in order:\n - Route: join `outbound.route` with \" → \" (e.g. \"PRG → MAD → BCN\"); for return flights show `inbound.route` on a second line.\n - Times & duration: `outbound.departureTime` → `outbound.arrivalTime` (local), formatted readably (e.g. \"12 Jun 06:05 → 09:30 (3h 25m)\") using `outbound.durationSeconds`; add the `inbound` equivalents for return flights.\n - Cabin: `outbound.cabinClass` (e.g. \"Economy\").\n - Price: `priceFormatted`.\n - Booking link: `bookingUrl`.\n\nFinally, summarise the best price and the shortest option, give a recommendation, and end wishing the user a nice trip with a short fun fact about the destination!", "inputSchema": { "properties": { "adults": { "default": 1, "description": "Number of adults (12+)", "ge": 1, "le": 9, "title": "Adults", "type": "integer" }, "adults_hand_bags": { "anyOf": [ { "items": { "maximum": 1, "minimum": 0, "type": "integer" }, "maxItems": 9, "type": "array" }, { "type": "null" } ], "default": null, "description": "Cabin (hand) bags per adult, one entry per adult (each 0-1), e.g. [1, 1]", "title": "Adults Hand Bags" }, "adults_hold_bags": { "anyOf": [ { "items": { "maximum": 2, "minimum": 0, "type": "integer" }, "maxItems": 9, "type": "array" }, { "type": "null" } ], "default": null, "description": "Checked (hold) bags per adult, one entry per adult (each 0-2), e.g. [1, 0]", "title": "Adults Hold Bags" }, "allow_diff_airport_connection": { "default": true, "description": "Allow connections that change airports within the same city", "title": "Allow Diff Airport Connection", "type": "boolean" }, "allow_overnight_stopovers": { "default": true, "description": "Allow overnight (red-eye) layovers", "title": "Allow Overnight Stopovers", "type": "boolean" }, "allow_self_transfer": { "default": true, "description": "Allow self-transfer (virtual interlining) connections between separate tickets", "title": "Allow Self Transfer", "type": "boolean" }, "atime_from": { "anyOf": [ { "ge": 0, "le": 23, "type": "integer" }, { "type": "null" } ], "default": null, "description": "Earliest outbound arrival hour (0-23, local)", "title": "Atime From" }, "atime_to": { "anyOf": [ { "ge": 0, "le": 23, "type": "integer" }, { "type": "null" } ], "default": null, "description": "Latest outbound arrival hour (0-23, local)", "title": "Atime To" }, "cabinClass": { "anyOf": [ { "enum": [ "M", "W", "C", "F" ], "type": "string" }, { "type": "null" } ], "default": null, "description": "M=economy, W=premium economy, C=business, F=first", "title": "Cabinclass" }, "children": { "default": 0, "description": "Number of children (2-11)", "maximum": 8, "minimum": 0, "title": "Children", "type": "integer" }, "children_hand_bags": { "anyOf": [ { "items": { "maximum": 1, "minimum": 0, "type": "integer" }, "maxItems": 8, "type": "array" }, { "type": "null" } ], "default": null, "description": "Cabin (hand) bags per child, one entry per child (each 0-1), e.g. [1]", "title": "Children Hand Bags" }, "children_hold_bags": { "anyOf": [ { "items": { "maximum": 2, "minimum": 0, "type": "integer" }, "maxItems": 8, "type": "array" }, { "type": "null" } ], "default": null, "description": "Checked (hold) bags per child, one entry per child (each 0-2), e.g. [2]", "title": "Children Hold Bags" }, "currency": { "default": "EUR", "description": "Currency code (e.g. EUR, USD)", "maxLength": 3, "minLength": 1, "title": "Currency", "type": "string" }, "departureDate": { "description": "Departure date in dd/mm/yyyy — the day to fly, or the earliest date of a range (see departureDateTo)", "maxLength": 10, "title": "Departuredate", "type": "string" }, "departureDateFlexDays": { "default": 0, "description": "Search +/- this many days around departureDate (symmetric).
