This month, I will be flying to the USA for a nice holiday on the west-coast. I will fly from Düsseldorf to San-Francisco and I want to bring my MacBook Retina 12" with me.

Is it possible to charge the MacBook via USB-A to USB-C on built-in USB port in the airplane? Or will the power-output not be sufficient enough?
 
The USB port is probably going to be 5 watts at most. It'll trickle-charge the laptop at best. Why wouldn't you use a regular power port on the plane and a power adapter?

check on seatguru.com and see what sort of power is available at your seat.

I'll post since I've actually done what you're asking, but flying cross-country rather than overseas.

The USB port provided enough power to maintain the Macbook's charge while in (light) use but didn't really add to it. I'd recommend also having your mains charger available just in case.
