Why wasn't my flight parsed from the e-ticket I sent to just@add.flights?

Most likely it was not in English, or it was a PDF attachment.

Tickets are best parsed in English when done from messages with no PDF attachments, and when they are linked to a Gmail account, whether the e-ticket is sent from Gmail. We are working on an algorithm to solve this issue.

You can also include the sender's email (airline, travel agency, etc.) on this form to help us maintain it in the future.

How do I connect my Gmail account?
