Well it's kinda normal sized I guess... or in fact a smaller considering they're huge in real life!!!!!!

It's not finished at the moment, Just gonna complete the shell first and I guess the interior will come after?

and the exterior too

Load the save, get onto your app data > .minecraft > saves > (place folder in there)

It is empty for you to decorate on the out and inside if you guys want.

I recommend a flying mod!

=UPDATE=
I've added windows by request and made the wings 1 block longer on each side.

This world save is for my other project called 'Small house Small surprise' so when logging onto the world you have a path to chose either the airplane or house! you can check out my other project my clicking my profile.

Thanks
