flight_explorer.py

"""
Script to help you find a cheap stopover destination between two fixed dates / cities.

Example usage:
python flight_explorer.py -f "LAX" -t "PRG" -d "2019-01-13" -a "2019-01-18"

In the above example, you know you want to leave LAX on 1/13 and be in PRG on 1/18.
This leaves you a few days to stop somewhere in between, so you want to find a city X with
two cheap one-way tickets: (LAX -> X) on 1/13 and (X -> PRG) on 1/18

The idea is to "explore" all flights leaving LAX on 1/13 (tab 1), "explore" all flights leaving PRG (*)
on 1/18 (tab 3), and visually spot a city that cheap to fly to from both locations.

Once you have a candidate city, look up actual tickets from LAX -> X (tab 2) and X -> PRG (tab 4).

(*) Why does tab 3 involve exploring flights OUT of PRG, when what we really want is to fly INTO PRG?
Unfortunatly, google maps doesn't let you "explore" flights arriving TO a city. The idea here is that
cost of flying A -> B on a given date is a good provy for the cost of flying B -> A.
