Thank you very much, Capt Quirk. Yes, I know that the function to import aircraft is not yet active, in the interface of the program. I hope developers will make it work soon. However, it is possible to import new planes and airlines by working on the various Excel files, and then import and compile air traffic with Traffic Global, obviously always acting with great caution when working on Excel. I think the structure of this program is superb and allows you to run almost anything, after learning it well. Huge potential. The critical comments on this programme, which I have read in other debates, are absolutely undeserved.
Below is another example of how it is possible to import an airline, assigning it an aircraft and a livery.
Flight plans for this airline already exist, but I added one with airport and custom time for testing.
