Flight to Calendar by jsantos42

A Firefox extension that extracts flight details from airline booking pages and downloads them as ICS calendar files.

How is this useful to me?
Several airline websites do not provide ICS files for their flights or, if they do, are rather incomplete. I found myself repeatedly having to create calendar events for my flights that respected both timezones (departure and arrival), that would aggregate all the needed info, and that would have timely reminders. This extension is an automation of that!
I have open sourced the code for full transparency, and will be adding more airlines as I feel the need for it. Feel free to contribute and add more airlines that you require.

Notes
- This extension has only been tested with English versions of the airline websites. Other languages may work but are not guaranteed.
- This extension relies heavily on the airlines website's CSS selectors, so if they change their structure the extension will naturally stop working with that specific website! If you do find a bug, please let me know, I'll fix it ASAP.
