@josekalel: I think the size of the terminal is kept in check for price reasons more than anything. This is a $100 set, and while bigger and pricier City sets exist, they tend to be few in number. What's more, the disadvantage to having a plane wide enough to seat two rows of passengers is that it inevitably takes up a big portion of the budget even for a larger set like this one. If the set were just the airport with no plane, then the terminal could probably be around twice this size at the very least… but then the set would not offer such a complete play experience.
Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS).[12][30] As of September 2008, Lego engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimised by way of mould flow and stress analysis. Prototype moulds are sometimes built before the design is committed to mass production. The ABS plastic is heated to 232 °C (450 °F) until it reaches a dough-like consistency. It is then injected into the moulds at pressures between 25 and 150 tonnes, and takes approximately 15 seconds to cool. The moulds are permitted a tolerance of up to twenty micrometres, to ensure the bricks remain connected.[33] Human inspectors check the output of the moulds, to eliminate significant variations in colour or thickness. According to the Lego Group, about eighteen bricks out of every million fail to meet the standard required.[37] Lego factories recycle all but about 1 percent of their plastic waste from the manufacturing process. If the plastic cannot be re-used in Lego bricks, it is processed and sold on to industries that can make use of it.[38][39] Lego has a self-imposed 2030 deadline to find a more eco-friendly alternative to the ABS plastic it currently uses in its bricks.[40]

I did prefer the previous 3182 airport set as it had a lot more components. But, I realise that it makes more business sense to offer a little less than raise the price of an already expensive product. However, 60104 is still a nice set and is often very well discounted in the UK so, I ordered a pallet load from Tesco during their 3-for-2 which made them a half-priced no-brainer ;-)

Manufacturing of Lego bricks occurs at several locations around the world. Moulding is done in Billund, Denmark; Nyíregyháza, Hungary; Monterrey, Mexico and most recently in Jiaxing, China. Brick decorations and packaging are done at plants in Denmark, Hungary, Mexico and Kladno in the Czech Republic. The Lego Group estimates that in five decades it has produced 400 billion Lego blocks.[41] Annual production of Lego bricks averages approximately 36 billion, or about 1140 elements per second. According to an article in BusinessWeek in 2006, Lego could be considered the world's No. 1 tire manufacturer; the factory produces about 306 million small rubber tires a year.[42] The claim was reiterated in 2012.[43]

Next we have the two Jet Pilots, one female and one male, both of which have identical torsos and helmets. The dark blue torsos, which are unique to this set, are printed with a nice design featuring a red jet with a red, white and gold jet wake plus gold jet insignia on the left breast. The white helmets incorporate a trans-black visor which can be raised and lowered; the helmets feature a print consisting of a star flanked with gold stripes, and like the torsos they’re currently exclusive to this set.
I like the nod to the classic LEGO Ideas Book with the 'Follow Me' sticker, but overall I think the F-18 type jet is redundant, making the whole thing over-priced. Had it been presented in a different colour scheme from the Viggen, and maybe a bit of a sleeker or more agile design in itself, it might have been a worthwhile inclusion. But as it is, it just superficially looks like two fairly similar aircraft, and thus quite a bit less value for money as a set.
The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932.[7][8] In 1934, his company came to be called "Lego", derived from the Danish phrase leg godt, which means "play well". In 1947, Lego expanded to begin producing plastic toys.[9] In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based on the Kiddicraft Self-Locking Bricks, which had been patented in the United Kingdom in 1939[10] and released in 1947. Lego had received a sample of the Kiddicraft bricks from the supplier of an injection-molding machine that it purchased.[11] The bricks, originally manufactured from cellulose acetate,[12] were a development of the traditional stackable wooden blocks of the time.[9]
The box set weighs a little over 2kg and has about 694 pieces in total, including 6 minifigures: a pilot, 3 airport workers, a male and a female passenger. The whole build would get you almost an entire airport facade with a pretty big passenger plane, an airport/control tower build, and an airport service car that tows with it a luggage, fuel and and mobile stairway.
I would also have liked a proper Ant-Man minifig – we get a micro Ant-Man, Giant-Man but not a regular-sized Ant-Man. There is a minifigure-sized Scott Lang hole in this set, and I think LEGO have wasted a great opportunity inserting a really popular and coveted minifigure into their flagship Civil War set. I would even gladly trade Cap and Bucky for one Ant-Man minifig.

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.
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).
Compared to other major European hub airports, like Charles de Gaulle or Heathrow, CPH has a similar number of connections, but is much smaller in both actual size and passenger volumes, and can provide a calmer, more pleasant experience. Its location in the south of Scandinavia makes reaching most European destinations reasonable, and flying to destinations in the Baltic region and in Eastern Europe generally only takes half the time as from major hub airports in Western Europe.
