This set has essentially all that's needed for airplane-related play: the plane, an airport terminal, and a service vehicle. And each part of the set is quite detailed. The plane feature a galley and a toilet; the service vehicle has stairs, a baggage trailer, etc; and the terminal has revolving doors, security check, and a baggage conveyor belt. The building process is also well planned out and documented. The child is eased into building by starting out with the service vehicle, then comes the plane, and last the terminal, which can be challenging.
Copenhagen Airport is a compact airport with two terminals for check-in, but with a common post-security departure and transfer area, thus making transfers very smooth. The airport handles in excess of 25 million passengers a year, which puts it in the same league as Zurich and Vienna. It has also consistently topped the charts for Nordic airports, serving as a European and intercontinental hub for all of them due to its location.
Other airlines offering intercontinental connections to Copenhagen are SAS's Star Alliance partners Singapore Airlines (to Singapore), Air Canada (to Toronto) and Thai Airways (to Bangkok Suvarnabhumi and Phuket), as well as competing SkyTeam carrier Delta with a seasonal connection to JFK and Pakistan International Airlines to Islamabad and Lahore.
Almost all major European carriers have a connection to Copenhagen from their main hubs. As Denmark holds sizable immigrant communities from various European countries, even smaller carriers have frequent connections to the likes of Sarajevo or Belgrade. Copenhagen Airport has been seeing increased traffic from low-fare carriers since the launch of the dedicated CPH Go section of the airport (with common check-in and security with other airlines, but separate gates and waiting area). Airlines using CPH Go include EasyJet, Ryanair, Transavia, and WizzAir, although the latter only for selected destinations, with the majority of its flights to the Øresund area landing at Malmö Sturup Airport instead.
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.
