Thanks for your help! Can you make one small change to FlightInfo please?

This breaks binary compatibility, and there are scenarios where that matters. Could you add an overload with the additional parameters instead of changing the existing public constructor? The original constructor can chain to the new one.

Yes Sure! Sorry for that, I am not a daily C# coder, and I need to warm up.
