SAS-PRICES-PY: Python Package for Fetching SAS Flight Prices

Overview

SAS-PRICES-PY is a Python package for interacting with SAS (Scandinavian Airlines) flight pricing APIs. It provides functionality to fetch and process flight data, including round-trip prices for specified origins, destinations, regions, and durations. Designed for efficiency, the package supports asynchronous requests and advanced filtering.

⚠️ Disclaimer: This package is in no way affiliated with Scandinavian Airlines.

Features

• Cheapest Round Trips:

  • Fetch the cheapest round-trip prices for specific destinations or regions.
  • Filter results by origin, destination, and trip start date.

• Monthly Prices:

  • Retrieve monthly outbound and inbound prices for specific origin-destination pairs.
  • Calculate combined round-trip prices for selected months.

• Trips by Length:

  • Find the cheapest trips of a specified duration (e.g., 2-day trips).
  • Search across all destinations or specific regions.

• Batch Request Optimization:

  • Use asynchronous requests for faster data retrieval when fetching multiple destinations.

• Error Handling:

  • Handle API failures, empty responses, and invalid data gracefully.

Installation

Install SAS-PRICES-PY via pip:

pip install sas-prices-py

---

Usage

1. Initialize the SAS Client

from sas_prices_py import SAS

sas = SAS(market="gb-en")  # Default market: "gb-en"

2. Fetch Cheapest Round Trips

trips = sas.get_cheapest_round_trips(region="Europe", origin="LHR", start_date="2025-01-01")
print(trips)

3. Fetch Monthly Round Trip Prices

monthly_trips = sas.get_monthly_round_trips(origin="LHR", destination="CPH", year_month="202501,202501")
print(monthly_trips)

4. Fetch Cheapest Trips by Length

trips = sas.get_cheapest_trips_by_length(origin="LHR", destination="CPH", year_month="202501,202501", trip_length=2)
print(trips)

5. Fetch Cheapest Trips Across All Destinations

trips = sas.get_cheapest_trips_by_length_all_destinations(
    origin="LHR", year_month="202501,202501", trip_length=2
)
print(trips)

Development Notes

Key Features

1. Batch Requests:

   • Optimized with asynchronous requests to reduce API call latency.

2. Dynamic Filtering:

   • Filter by region, origin, destination, and trip duration.

3. Customizable Markets:

   • Set the market during initialization (gb-en, us-en, etc.).

Known Limitations

• Empty responses may occur if no flights are available.
• Network-related errors can slow or fail batch requests; retry mechanisms may improve performance.
