That's Alex from App in the Air team. Thanks for your request. At the moment, we can integrate into auto mode the flights not more than 5 years of old. The reason is that for flights old data may not be accurate. Plus we verify some fields like airport code, that can be changed for years. So in the reasons that the data quality may not be good for older flights, you can just add them manually. You can save the data to the Excel file and then send it to firstname.lastname@example.org.
