Is your feature request related to a problem? Please describe.
Since there are planes now in MTR, there should be airport utilities available for the mod.

Describe the solution you'd like
There should be options to put airport utilities such as: Luggage carts, luggage, and security checkpoint items (this one isn't necessary because it may take a long time).
Additional Information
Add any other context or screenshots about the feature request here.
For the luggage carts and luggage, there should be an option to customize their textures.

The main idea of this mod is railway. Airlines are extend contents, and author said that except if there is a huge bug that can cause crash, he won't update this facility anymore.
You can make a mod about airport utilities by yourself.

Okay, thank you!
