How flight search works

​
One-way and round-trip

Search for flights using IATA airport codes. The platform fetches results from Google Flights via SerpAPI. Request example: 
{
  "origin": "YYZ",
  "destination": "BER",
  "departure_date": "2026-06-15",
  "return_date": "2026-06-22",
  "adults": 2
}
Response structure: 
{
  "ok": true,
  "offers": [
    {
      "id": "serp-0-token123",
      "totalAmount": "850",
      "totalCurrency": "USD",
      "owner": {
        "name": "Lufthansa",
        "iataCode": "LH"
      },
      "bookUrl": "https://www.google.com/travel/flights?...",
      "departureToken": "token_for_return_flights",
      "slices": [
        {
          "origin": {
            "name": "Toronto Pearson International Airport",
            "iataCode": "YYZ"
          },
          "destination": {
            "name": "Berlin Brandenburg Airport",
            "iataCode": "BER"
          },
          "duration": "8h 30m",
          "segments": [
            {
              "operatingCarrier": {
                "name": "Lufthansa",
                "iataCode": "LH"
              },
              "flightNumber": "LH470",
              "departingAt": "2026-06-15T18:00:00",
              "arrivingAt": "2026-06-16T08:30:00",
              "origin": {
                "name": "Toronto Pearson International Airport",
                "iataCode": "YYZ"
              },
              "destination": {
                "name": "Berlin Brandenburg Airport",
                "iataCode": "BER"
              },
              "duration": "8h 30m"
            }
          ]
        }
      ]
    }
  ]
}
Round-trip searches use a two-step flow: first select an outbound flight, then the platform fetches return options using the departureToken from your selected outbound offer.
Build complex itineraries with up to 6 legs. Each leg requires origin, destination, and departure date. 
{
  "slices": [
    {
      "origin": "JFK",
      "destination": "LHR",
      "departure_date": "2026-07-01"
    },
    {
      "origin": "LHR",
      "destination": "CDG",
      "departure_date": "2026-07-08"
    },
    {
      "origin": "CDG",
      "destination": "JFK",
      "departure_date": "2026-07-15"
    }
  ],
  "adults": 1
}

​
Flight status tracking

Look up live flight information by flight number and departure date. The platform checks AeroAPI (FlightAware) and falls back to Aviationstack. Endpoint: POST /api/flights/status Request: 
{
  "flight_number": "AC123",
  "departure_date": "2026-06-15"
}
Response: 
{
  "ok": true,
  "flight": {
    "flightNumber": "AC123",
    "airline": "Air Canada",
    "airlineLogoUrl": "https://www.gstatic.com/flights/airline_logos/70px/AC.png",
    "routeFrom": "YYZ",
    "routeTo": "LHR",
    "departureAirportName": "Toronto Pearson International Airport",
    "arrivalAirportName": "London Heathrow Airport",
    "departureLocal": "6:00 PM",
    "arrivalLocal": "6:30 AM",
    "departureTimezone": "America/Toronto",
    "arrivalTimezone": "Europe/London",
    "duration": "7h 30m",
    "terminalGate": "Dep T1 G42 · Arr T2",
    "stops": 0
  }
}
The status API auto-fills airline, route, times, timezone, and gate information when available. Use this to quickly add confirmed flights to your trip.

​
Filtering and sorting results

The flights UI includes:
  • Airline filter: Show only flights from a specific carrier
  • Max price filter: Set an upper price limit
  • Sortable columns: Route, date, departure time, arrival time, duration, stops, cost, airline

​
Booking options

For SerpAPI results with a bookingToken, resolve the direct booking URL: Endpoint: POST /api/flights/serp/booking-options Request: 
{
  "booking_token": "token_from_offer"
}
Response: 
{
  "ok": true,
  "url": "https://www.google.com/travel/flights/booking?...",
  "post_data": null
}
Most offers include a bookUrl that links directly to Google Flights with the flight pre-selected. Use the booking-options endpoint when you need the exact POST data for programmatic booking.

​
Saving flights to your trip

Each searched flight can be saved with:
  • Route (origin → destination)
  • Departure and arrival times
  • Duration and stops
  • Airline and cost
  • Booking URL
Saved flights persist in your trip and sync to the itinerary planner.

​
Explore mode

Find cheap flights from your origin to multiple destinations across a date range. Endpoint: POST /api/flights/serp/explore Request: 
{
  "origin": "YYZ",
  "date_from": "2026-06-01",
  "date_to": "2026-06-07",
  "adults": 1
}
The API searches up to 5 default destinations (JFK, LHR, CDG, YYZ, LAX) or a single specified destination, returning the cheapest option for each date.
Explore mode is limited to 14 dates and returns only the best offer per destination per date. Use this to find the most affordable travel window.

​
API configuration

Flight search requires:
  • SERPAPI_API_KEY (or SERP_API_KEY) for search and booking options
  • AERO_API_KEY (or AEROAPI_KEY) for status lookup (primary)
  • FLIGHT_STATUS_API_KEY (or AVIATIONSTACK_API_KEY) for status lookup (fallback)
Without these keys, the respective features return a 503 service unavailable error.
