Custom Deep Learning for Unstructured Email Data Extraction

For a Company Providing Private Aircraft Charter Services

The Challenge: Automating Unstructured Private Charter Requests

Every day, people send out hundreds of emails requesting private aicrafts for charter. On of our clients, True Aviation, wanted to connect people who had private aircrafts available along a specific route with people who wanted to travel on that route. For this, they required an interface that allowed email requests to be searchable by arrival and departure airports, dates & times, and aircraft types.

Our Solution: Deep Learning-Powered Information Retrieval

Since different people put in requests in different formats and writing styles, using a traditional rule-based parser was not a viable option.

Recognizing that standard rule-based parsers fail with varied inputs, we engineered a custom Deep Learning model (a powerful form of Machine Learning). This allows the system to automatically extract desirable information (departure, arrival airports, dates, etc.) and display it in a searchable format, regardless of the writing style.

The Two-Stage Extraction Strategy

One major challenge was that a single request often included multiple routes (e.g., the person wants to go from airport A to B on a specific date, and then from B to C on some other date).

To solve this, our solution follows a two-stage strategy:

  1. Stage One: Extracts the different airports, dates, and times present in the request.
  2. Stage Two: Identifies which arrival airports, dates, and times link to which departure airports, correctly mapping the complex, multi-leg itinerary.

Our final deliverable was a real-time, web-based interface which receives requests, processes them using our machine learning model, and displays the extracted data.

Results & Operational ROI

Our AI model achieved an extraction accuracy of around 98%, translating directly into saving dozens of hours spent each week by private aircraft charter agencies manually going through requests.

This significant enhanced operational efficiency allows human agents to shift their focus to high-value client relations and booking confirmations over manual data processing.
