Thanks for the comments, and in response to your question, I just got the lego city cargo plane and mail plane sets for Christmas, So I'll be able to upload pictures of the airport with planes in a few days.
I´m currently still building my third cargo jet, which is gonna become part of a big airport layout I want to build. I´m so excited about it - and my brother just sold me all of his Legos..:) So there will be more stuff to build...:) I have so many ideas it´s crazy... Best regards from Germany, Steffen
A nice little airport! Looks great and works well with small planes. For big ones, it´s too small though. I would make a non-commercial, maybe private airport out of it. Anyways, cool creation! Do you have planes already? Steffen
