FlightSearchFilters

The main model for configuring flight searches.

from fli.models import (
    FlightSearchFilters, FlightSegment, Airport,
    SeatType, MaxStops, SortBy, TripType, PassengerInfo
)

# Create flight segments for round trip
flight_segments = [
    FlightSegment(
        departure_airport=[[Airport.JFK, 0]],
        arrival_airport=[[Airport.LAX, 0]],
        travel_date="2026-06-01",
    ),
    FlightSegment(
        departure_airport=[[Airport.LAX, 0]],
        arrival_airport=[[Airport.JFK, 0]],
        travel_date="2026-06-15",
    )
]

filters = FlightSearchFilters(
    trip_type=TripType.ROUND_TRIP,
    passenger_info=PassengerInfo(adults=1),
    flight_segments=flight_segments,
    stops=MaxStops.NON_STOP,
    seat_type=SeatType.ECONOMY,
    sort_by=SortBy.CHEAPEST
)

Validation Rules:

  • Flight segments must have different departure and arrival airports
  • Travel dates cannot be in the past
  • For round trips, exactly two flight segments are required
  • Passenger counts must be valid (at least one adult)
