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.

In June 2013, it was reported that Warner Bros. was developing a feature film adaptation of Lego Ninjago. Brothers Dan Hageman and Kevin Hageman were attached to write the adaptation, while Dan Lin and Roy Lee, along with Phil Lord and Chris Miller, were announced as producers.[87] The film, The Lego Ninjago Movie, was released in September 2017.[88] A computer-generated animated series based on Lego Ninjago: Masters of Spinjitzu began in 2011, and another based on Legends of Chima began in 2013. A television series of Lego City has also been announced.[89]
The railway station, 1 Københavns Lufthavn, Kastrup Station (sometimes called CPH Airport Station and wrongly Kastrup Station), is located in Terminal 3. The station has frequent connections to Copenhagen and Malmö, as well as InterCity trains for the rest of Denmark and a few daily SJ 2000 express trains for Stockholm. The frequent Øresund trains between Copenhagen and Malmö continue in Denmark to Elsinore and in Sweden to a number of destinations in Scania and other parts of Götaland. The travel time to Copenhagen Central Station is 12 minutes, and 20 minutes to Malmö Central Station.
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.
