Having destroyed a few model decals, I wonder how airliner decals are applied so precisely. They have the triple challenge of having to be remarkably thin while also sticking incredibly firmly to the fuselage skin without a single bubble. How do they do it?

They're not really the same construction as model decals...more like giant stickers. Way more durable.

I think they roll them on and "squeegee" as they go, like when you apply protective film to an iPhone, just much much larger.

They are just big peel off sticker. Only difference, due to the size they have small holes in them to allow the air out.. and come in many pieces.

It's not quite as glamorous as you make it out to be! It's a job I try to avoid on an A-check, simply because it's a pain to get it right, and I'm way too OCD to be tasked with it.
Basically, it's just a sticker that you press on. And they don't last that long; at least, not the ones on the bottoms of the wings, anyway. We replace the same ones every month sometimes.
The weird thing is that sometimes you don't notice they're gone- the engine cowl just looks normal without it. But that's what Quality Control is for.

Very carefully.  

One point to mention they are not always a single piece "sticker". Some types of decal can be separate areas of logo, lettering, etc held spatially correct by the backing paper, especially where the background colour is intended to show through in places. You can get in a real mess unless very careful.



The glass isn't half empty, or half full, it's twice as big as it needs to be.

Yep the giant panda decal on the first 777 for FedEx was a real pain actually it was 2 decals one for each side. Thankfully I didn't have to do it
