Many risk and credit models for airlines rely on the departure date of the ticket.
Once that date has passed, the risk that the customer will not get their flight is considered to have lapsed - so the funds are safe to release.
The problem is many transactions are processed with an invalid date or without a departure date being provided.
That means you get less money and you get it later than you should.
Why is it happening?
While almost all tickets purchased have a departure date, that vital data can drop out at several points of the transaction.
What can you do about it?
If you can identify where in the process the departure date is dropping out, you can fix the problem so it doesn’t happen again.
