American Airlines seat viewer

aa-seats.py

#!/usr/bin/env python3

# This script takes one parameter, an American Airlines flight number.
# It also requires a FlightLabs API key to be stored in FLIGHTLABS_ACCESS_KEY,
# you can get one at https://app.goflightlabs.com/.

# It will lookup additional flight details from the flight number, and then
# open a web page to the AA seat map tool, passing the proper URL parameters
# to view the seat map for the provided flight.

# It requires dateutil and requests to be installed before use.
