Airport Expansion

If you complete three of Norbert's challenges a day you have the chance to win them along with runway pieces, land tokens and a hangar.

you get it by sending a character on a flight that solves the little riddle you see on the flight screen.
complete the task 3 times and you get another piece of airport.
thats the short version.
Here is LPN's guide to the airport tasks https://forums.ea.com/en/the-simpsons-tapped-out/discussion/91558/destination-springfield-norberts-adventure-tasks/p1 for MUCH more detail.

You need to complete Norbert's tasks to get them.

Thanks. I've been completing the tasks and getting land expansion tokens. I guess I'll just have to wait and keep completing tasks. I was hoping there was a way to buy the expansions since I've already purchased all of the available land.

I kinda have the same issue. In the game it when I open the.suitcase it shows me winning the gates but in fact I won the hanger. So I'm wondering if I can still win the gates and have both.

I've only gotten like idk...3 pieces. At this speed I don't know if I'll ever finish the run way....unless I 'do' something else to get the pieces.
