This is a good set if you want an airport. The set includes a big plain and a terminal. The terminal has a control tower, check-in, luggage handler, fuel tank, ... I expanded my terminal and built it on a 32x32 baseplate and used the 2 grey 16x16 plates for the roof. The backside is not completely closed. Otherwise is the luggage belt is not accessible with my hand. I added 2 extra seats in the plane. Normally you have 6 seats in the plane, but I raised it to 8. I wanted more than 8 but that is almost not possible. The plane is brought with a big brick which includes the middle of the plane and the 2 wings and that one limits the possibilities. The toilet in the plane is still on the backside.

The remainder of the build is the control tower and terminal building. First there is a metal detector screener leading to the waiting/secure area of the airport, which seems taller than it needs to be for the minifigures. I think the same effect could have been made with half the height, except that would not allow for an impressive height for the overall tower. However it does seem to be similar to many modern airports with the high ceilings. This area also seems to be someplace to check luggage as evidenced by the rather nifty conveyor belt that comes in a full part. The moving parts of the set include a revolving door (a very tall one, for the first floor) that leads from the secure area of the airport out to the tarmac, and of course the conveyor belt.
City is the thematic title under which most Town-related System sets were released from 2005 and onward. There are numerous sets that are associated with Construction, Police, Fire, Emergency, Train, Airport, Transportation, Cargo, Traffic, Coast Guard, Farm, Great Vehicles, Mining, and Space. European catalogs featured another theme called City in the years 1999 to 2000, which was referred to as City Center in American catalogs.
Every good airport needs a hangar for the planes, and this is no exception. The satisfactory hangar included here does come across as rather basic, and while it doesn’t detract from the overall package, it isn’t going to swing your decision over whether to purchase this (and truthfully, I think you would have already made that decision before you come to the hangar). The design itself is simple, with the build unlikely to take you more than 10 minutes. That being said, it is a well-built piece and doesn’t feel flimsy, which was the impression I had when I first saw a picture of it. The criss-cross pieces towards the base give it a firm foundation, and there are plenty of long pieces which add further stability to it. Plane-wise, it is best suited for the old-fashioned vehicle, with the orange colouring in the design going well with the plane. Only a couple of stickers in use here, with just the AIRSHOW HANGAR words needing to be added.
The intelligent brick can be programmed using official software available for Windows and Mac computers, and is downloaded onto the brick via Bluetooth or a USB cable. There are also several unofficial programs and compatible programming languages that have been made to work with the brick, and many books have been written to support this community.[52]
Bag 7 finished off the front facade adds in a metal detector and the baggage check-in station.  I guess you enter from the right and then maybe the revolving doors are where you can walk out to the plane.  I'm not really sure anymore.  The conveyor belt is a nice addition to the set for playability and is set up so you can pull the baggage cart right next to it.  
Parking capacity at Copenhagen Airport was greatly expanded in 2015 with the construction of a new lot as one of the first phases in an ambitious airport expansion plan scheduled to roll out in the coming decades. There are several lots: those near the terminals are very expensive, while the further-flung ones are cheaper (but have free shuttle bus service to the terminals).
