This was bought for my son's 5th birthday. If your kid likes to really play with the sets like mine does (not just bought for building it) be aware that the door of the airplane likes to pop off if it is not opened/closed just the right way with gentle hands. My son is a typical rambunctious boy and is not great at opening/closing things gingerly, so the door presents a bit of a problem for him. He doesn't have the dexterity or patience to snap the two tiny joint pieces onto the little pole just so yet, so whenever the door comes off he gets frustrated and needs help. Which is fine, we help him and he will eventually learn to do it himself, but just wanted to make y'all aware of this in case you have someone who is picky about the door opening and closing easily/correctly :) I know some little ones get fussy about these things!
Apart from that, both carriers have extensive networks within Europe and the Mediterranean (including North Africa and the Middle East). SAS flies to most European capitals, and has a particularly dense network of connections across the Baltic Sea, to Finland, Estonia, Latvia and Lithuania, as well as to Poland, where it serves the majority of even small airports. There is also a fairly good network of connections to the United Kingdom and, perhaps surprisingly, to Italy, where even smaller airports like Bologna are served.
Copenhagen is not only the main airport for the densely-populated Øresund region, but also the main air transportation hub for Scandinavia, the main hub for the joint Danish-Swedish-Norwegian carrier SAS Group, and one of Europe's major hubs. There is a large number of intercontinental connections to Copenhagen, as well as a dense network of short-haul connections from Copenhagen to destinations throughout all of Europe, especially the Nordic countries.
The main constituents of the set are a tanker truck, three aircraft and a hangar. Each of these gets its own instruction booklet and bags of elements. First up is the tanker truck (below) which at only four studs wide and less than ten studs in length reminds me of the 4-stud wide vehicles of my youth. This impression is reinforced by the inclusion of a couple of late 70’s-style 2 x 4 mudguards in the build.
Bag 6 starts the airport terminal. Like most CITY builds, they are meant for play so it's really only half a building. It includes one minifigure and the revolving door entrance. While the entrance is cool looking, it's about twice the height of a minifigure and there isn't enough physical space for one actually to fit through the door. I'm not a fan of the design.
Billund Airport had its beginning in 1961 when the son of the founder of the Lego Group, Godtfred Kirk Christiansen, established a private 800-meter long runway and hangar north of his factory in Billund. With Christiansen as a key driver, more of the neighbouring municipalities were included in the group of owners, and it was planned that the airport should be expanded to a regular public airport.
