Here's how the program works. First, I have a Google sheet which keeps track of the locations that I want to visit and a price cutoff.
It takes data from my Google sheet with lots of different locations and their lowest prices and feeds that into a flight search API, which runs searching through all of the locations. Looking for the cheapest flight in JKIA in the next six months.
When it comes up with a hit and it finds a flight that's actually cheaper than my predefined price, then it sends that date and price via Twilio SMS module to my mobile phone. I can then book the flight if i wish to.
