Flyan 0.2.0

Open source unofficial API wrappper to get flight data from RyanAir.

Flyan SDK

An open-source unofficial API wrapper to get flight data from Ryanair.

Installation

pip install Flyan

Or using uv:

uv add Flyan

Quick Start

from datetime import datetime
from flyan import RyanAir, FlightSearchParams

# Initialize the client
client = RyanAir(currency="EUR")

# Set up search parameters
search_params = FlightSearchParams(
    from_airport="DUB",  # Dublin
    to_airport="BCN",    # Barcelona
    from_date=datetime(2025, 8, 15),
    to_date=datetime(2025, 8, 20),
    max_price=200
)

# Search for one-way flights
flights = client.get_oneways(search_params)

# Display results
for flight in flights:
    print(f"Flight {flight.flight_number}: {flight.departure_airport.name} → {flight.arrival_airport.name}")
    print(f"Departure: {flight.departure_date}")
    print(f"Price: {flight.price} {flight.currency}")
    print("---")

Examples

Search by Country

# Search flights to any airport in Spain
params = FlightSearchParams(
    from_airport="DUB",
    destination_country="ES",
    from_date=datetime(2025, 9, 1),
    to_date=datetime(2025, 9, 7)
)

flights = client.get_oneways(params)

Filter by Time and Price

# Morning flights under €100
params = FlightSearchParams(
    from_airport="STN",  # London Stansted
    to_airport="DUB",    # Dublin
    from_date=datetime(2025, 8, 1),
    to_date=datetime(2025, 8, 5),
    max_price=100,
    departure_time_from="06:00",
    departure_time_to="12:00"
)

flights = client.get_oneways(params)

Error Handling

from flyan import RyanairException

try:
    flights = client.get_oneways(params)
    if not flights:
        print("No flights found for the given criteria")
except RyanairException as e:
    print(f"Ryanair API error: {e}")
except Exception as e:
    print(f"Unexpected error: {e}")

Explore Mode

Explore Mode answers the question "where can I actually fly from here?". It reads Ryanair's live network metadata once and exposes the reachable destinations from any airport, optionally grouped, filtered, or joined with the cheapest fare in a date window.

All methods below are available on both RyanAir and AsyncRyanAir.

List every destination

destinations = client.get_destinations("DUB")

for airport in destinations:
    print(f"{airport.iata_code} {airport.name} ({airport.country_code})")

Filter by country, region or city

# All Scottish airports DUB flies to
in_scotland = client.get_destinations_in_region("DUB", "SCOTLAND")

# All London airports DUB flies to (LGW, LTN, STN)
in_london = client.get_destinations_in_city("DUB", "LONDON")

# All Spanish airports DUB flies to
in_spain = client.get_destinations_in_country("DUB", "es")

Country codes are lowercase ISO2. Region and city codes come from the live network (uppercase, e.g. SCOTLAND, ANDALUSIA, COSTA_DE_SOL, LONDON, MILAN).

Group destinations

# {country_code: [airports]}
by_country = client.explore_by_country("DUB")

print(f"DUB flies to {len(by_country)} countries")
for country, airports in sorted(by_country.items()):
    codes = ", ".join(a.iata_code for a in airports)
    print(f"  {country}: {codes}")

# {region_code: [airports]}
by_region = client.explore_by_region("DUB")

Airports without a region_code are collected under the empty-string key, so callers can decide whether to surface or drop them.

Seasonal-only destinations

seasonal = client.get_seasonal_destinations("DUB")

Ryanair's seasonalRoutes list is sparsely populated upstream, so this often returns [] outside of summer/winter schedule transitions. The method is provided so callers do not need to peek at the raw route strings.

Destinations with their cheapest fare

explore_with_fares() joins the network destinations with a oneWayFares probe, so each destination comes back with its cheapest sampled Flight (or None if no fare was returned for that route in the window). It costs one network call plus one fare call.

from datetime import datetime, timedelta

start = datetime.now() + timedelta(days=14)
end = start + timedelta(days=7)

results = client.explore_with_fares("DUB", start, end, max_price=100)

priced = [d for d in results if d.fare is not None]
cheapest_first = sorted(priced, key=lambda d: d.fare.price)

for d in cheapest_first[:10]:
    print(f"{d.airport.iata_code} {d.airport.name}: "
          f"{d.fare.price} {d.fare.currency}")

Async usage

AsyncRyanAir mirrors every explore method:

import asyncio
from flyan import AsyncRyanAir

async def main():
    async with AsyncRyanAir() as client:
        by_country = await client.explore_by_country("DUB")
        print(f"{len(by_country)} countries reachable from DUB")

asyncio.run(main())

If you call multiple explore methods in a row, wrap the transport in CachingTransport so the network metadata is fetched once and reused.

Supported Airports

The SDK supports all airports in Ryanair's network. Airport codes must be valid 3-letter IATA codes. The live list is fetched from Ryanair's aggregate endpoint via client.get_network(); iterate network.airports for the full set.

Popular airports include:

• DUB - Dublin
• STN - London Stansted
• BCN - Barcelona
• MAD - Madrid
• FCO - Rome Fiumicino
• BRU - Brussels
• AMS - Amsterdam

Supported Currencies

The SDK supports multiple currencies. Some popular ones include:

• EUR - Euro
• USD - US Dollar
• GBP - British Pound
• CHF - Swiss Franc

See currencies.json for the complete list.

Rate Limiting

The SDK includes automatic retry logic with exponential backoff to handle rate limiting and temporary API issues. It will retry failed requests up to 5 times before giving up.
