About the Project

Convert an airline crew schedule pdf into iCalendar format using a Large Language Model. OpenAI's gpt-4o-mini is used to extract the schedule information. iCalender files are recognized by most calendar systems (iOS, Android, Google, ++) and will create the flights on your phone/device calendar.

The PDF schedule does not need to follow a very prescribed structured format.

Development performed mostly using AIMS eCrew pdf schedules. It may work on other systems' schedules. Feel free to suggest other systems.

Getting Started

Prerequisites

Obtain an OpenAI API key.

Make this available as an environment variable:

Alternatively specify the API key in a .env file.

Usage

CLI

To create the calendar file (schedule.ics) from a pdf schedule file (schedule.pdf):

crewcal extract schedule.pdf schedule.ics

crewcal --help shows a brief manual page.

Python Package

The following sript extracts the schedule from schedule.pdf and stores the icalendar file in schedule.ics file.

from crewcal.llm_extract import OpenAISchedule

sched = OpenAISchedule(schedule_path='schedule.pdf', to_icalendar_file='schedule.ics')

The resulting .ics file can be read by most calendar software.

Roadmap

• Add support for schedules from systems in addition to AIMS. I would be happy to look at suggestions, especially if you can provide sample schedules. Create a new issue to initiate a new request.
