Even though I understand the feeling of having such a large aircraft, landing in your airport you spent a few days perfectly creating.
I still believe it’s best to see how a smaller aircraft, yet still a large aircraft is implemented within the game to ensure that the game is fully prepared for the full implementation of the A380 or 747.
I personally would rather much more smaller types of aircraft like the 717, or the 767. But then this game is in Alpha.
I do expect them to come soon, with the implementation of catering to come soon, and cleaning later on, and also having a new aircraft developer I believe it will be shorter timespan than we think. Or I think.
