Hi guys, allow this newbee to this forum to say something about this.
Last year I started playing airport city on my laptop via facebook. That version doesn't really work (long story), but it did have this baggage hall phenomenon. It was about as useful as the duty free shop, or actually even less. I guess the developers are simply taking some "features" from other versions of the game and put it in the android and IOS games. However, a good feature in this facebook game was, amazingly, wait for it... a reserve hangar !! For as little as 60.000 coins you could get yrself a reserve hangar (level 3) for 10 planes enabling you to put planes in storage that you don't need for the moment. Now there's a feature that they should transfer to our environment...
A reserve hanger would be great.
