After World City's discontinuation in 2004, it was replaced with City as System's primary town-life related theme in 2005. However, unlike its predecessor, it was not limited to sets involving rescue services like Police, Fire or Coast Guard, but also introduced the first new construction site related sets since the discontinuation of City Center in 2000. In 2006, the first new airport set that included the first jetway since 6597 Century Skyway (1994) was released, as well as the first new hospital since 6380 Emergency Treatment Center from 1987. These releases expanded City to a scope only comparable to the original Town theme, and in 2009 it even went slightly beyond that, by introducing the first farm-related System sets. Also, in that year, City followed this route to release more truly civilian town life sets such as 7641 City Corner and 7639 Camper. In 2010 City released more civilian sets including 8403 Family House and 8404 Public Transport. In 2011 City re-introduced the Space sub-theme along with some new Harbour sets. In the first wave of 2012, City had forest police and fire sets as well as some more commercial/civilian sets. The second wave of 2012 featured the introduction of the Mining theme and respective sets, as well as a hospital. In the winter of 2013, Police and Fire sets were once again focused on but, contrary to those released in the previous year, were set in the city. In the summer of 2013, the Coast Guard and Cargo subthemes were brought back.
Lego operates 132 so-called "Lego Store" retail shops.[71] There are stores at the Downtown Disney shopping complexes at Disneyland and Walt Disney World Resorts as well as in Mall of America in Bloomington, Minnesota. The opening of each store is celebrated with weekend-long event in which a Master Model Builder creates, with the help of volunteers—most of whom are children—a larger-than-life Lego statue, which is then displayed at the new store for several weeks.[72]
Basically, the only thing that the two sets have in common is that they both have planes. However there is quite a bit of difference on the inside of the planes. There are a lot more details in the Friends plane. In addition to the seats, there is a rolling service cart complete with refreshments, emergency lighting as well as a larger galley and lav in the back of the plane.
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!

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.

The design on the jet pilots’ outfits are very good, with a darker blue colour scheme offset with a red/white/yellow stripe pattern on the torso. The requisite wings and plane emblem complete the look, with the star-emblazoned helmet the icing on the cake. However, as good as those outfits are, I think the bi-plane pilots’ attire is even better, with a swish darker red colour on the legs and above the waist, culminating in a flame-effect design merging into a white torso. The old-fashioned flying helmets and goggles look great and really compliment the overall figure design.
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.

This set is designed for children aged 6+, and one of the ways that it is suitable for them is the inclusion of separate instruction booklets and numbered bags for the different parts of the set (see my post about LEGO age range suitability here).  A younger modeller can build the plane or other item of their choice as soon as they open the box. It's not so much one big set as 5 different parts which make a whole scene. My 7 year old son chose to build a jet first of all...

@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.
I purchased this set the day it was released for my LEGO City, as an upgrade from my previous airport (10159 Airport from 2004). First off, the build is great and although it's not very challenging, it's exciting to see the plane come to life and the use of the big plane pieces (eg. the nose, the wings, the tail etc.) was new to me, though I know there have been a number of planes in the past that use these pieces. There are 4 instruction booklets (2 for the plane, one for the airport, and one for the luggage/fuel/stairs car), 8 numbered bags, and two separate bags with the bigger pieces in. This makes the build very easy to follow. The completed set is very grand (especially the plane) in scale, and great looking. It's nice to see that a different colour scheme been used for the plane as opposed to the usual red and white or blue and white colours as seen in previous sets. The plane is HUGE, with a wingspan of around 2 32-wide baseplates (bare this in mind if you want to make a runway). However, despite its huge size, the inside of the plane is very bare. There are 5 seats for the passengers, another one facing backwards which I presume is for the cabin crew (although there isn't a cabin crew minifigure, which would have been a nice addition), and two seats in the cockpit. There's a tiny bathroom at the back of the plane, and a small galley area at the front with a sink and cupboard. There's easily room for a sixth chair in the plane, which I think should have been included, and the space within the plane could've been arranged better to fully optimise the area. The airport terminal has a very nice modern look, and includes the revolving door, tower, waiting area, security scanner and check in desk with luggage conveyor. Although this sounds like a lot of features, the inside of the terminal is, again, very bare and the space could've been used better. There are only 4 seats in the waiting area, and a lot of the space is taken up by the revolving door. The operational conveyor belt for the luggage is a nice touch, though, and there is a fair bit of playability within. The service car is a nice addition to this set and gives it more playability. All the trailers (fuel, stairs and luggage) connect together and attach to the service car, which has a really cool "follow me" sign on the back. This is a really nice addition to the set. Overall, I really like this set because of how it looks and because there's plenty of opportunity for play, but I think a lot more thought could've gone into maximising the space within the plane and the airport. Some more minifigures would have been good, such as a member of the cabin crew, a check-in clerk and a security officer. The value for money is okay with this set, as you do get a lot of big pieces, but the bare interiors are a little disappointing for the price you pay.
Primary concept and development work takes place at the Billund headquarters, where the company employs approximately 120 designers. The company also has smaller design offices in the UK, Spain, Germany, and Japan which are tasked with developing products aimed specifically at these markets. The average development period for a new product is around twelve months, split into three stages. The first stage is to identify market trends and developments, including contact by the designers directly with the market; some are stationed in toy shops close to holidays, while others interview children. The second stage is the design and development of the product based upon the results of the first stage. As of September 2008 the design teams use 3D modelling software to generate CAD drawings from initial design sketches. The designs are then prototyped using an in-house stereolithography machine. These prototypes are presented to the entire project team for comment and for testing by parents and children during the "validation" process. Designs may then be altered in accordance with the results from the focus groups. Virtual models of completed Lego products are built concurrently with the writing of the user instructions. Completed CAD models are also used in the wider organisation, for marketing and packaging.[33]
Nice review, and it looks like a really nice set with a good mix of builds. The fact that I read the entire review without looking for the price speaks volumes for this in my opinion. The planes look good and I cannot see anyone from any age group who buys this not giving all three planes at least a quick test drive round the living room. One to add to my list.

I'm not sure what to make of the set yet. I like the planes (although that biplane really doesn't need the bubble canopy). The idea of adding a hangar is interesting and I don't mind that it's a bit open. But the fact that it'll only house one of the three planes is annoying. Having said that, I'm not sure what you could do about it. Tripling the hangar would make it big and boring and push the price up. Could they have done two planes and a double hangar?
Other than the planes, I do find it unfortunate that the Friends set focuses on shopping and food like so many Friends sets, and I also think it is unfortunate that the City terminal only has the basics of the airport structure in the control tower and service truck. Having a control tower for the Friends set would have been great. Having a gift shop/cafe for the City terminal would have been a worthwhile addition and not something we have seen in many City sets.
LEGO CITY has some recurring themes that can get old after a while and obviously are meant for younger LEGO fans.  The Fire and Police themes within CITY quickly come to mind as it seems like they have a new run each year.  The Airport theme is one of those that doesn't quite occur every year.  The last airport set was released in 2010 and was set #3182.  This year (2016) another airport was released.  #60104, Airport Passenger Terminal, was released on 1 August 2016 in the US.  It costs $99.99 in the US and contains 694 pieces or $0.144 per piece.  I picked the set up from Amazon at 20% off or $80 ($0.115 per piece).  Yay sales!  Onto the review...
