When an FBO processes AIR Card transactions through Avfuel, it’s important to be aware of Avfuel’s settlement timing.
If the FBO attempts to process a refund before 1:00 PM Eastern Time the next day, the system will return an error.
This is expected behavior and is related to Avfuel’s processing timeline—not a system or configuration issue.
Recommended Action
Wait until after 1:00 PM Eastern Time on the following business day before attempting to process the refund.
