I did one test IFS setup, added to 1 route. In detailed route finance I see interesting numbers:
In-Flight Service $67 (shouldn`t this be called profit?)
IFS Cost -
What am I selling to passengers if I don`t have any costs? There should be some IFS costs as I need to buy food to offer it on board. But looks like I get it for free and can sell. Maybe I don`t understand something correctly.
Then in next tab, Flight list is
IFS Revenue: $468
What are these numbers and where are they coming from?
