Hello flying friends.

I've been flying MSP - NRT - PVG a lot lately and since I have so much time on the plane, I'm interested in identifying the specific plane I'm on.

Is there a way, from the inside of the plane (without scratching my initials in the bathroom) to identify the specific plane? e.g. Serial Number, etc.

I feel like I'm flying on the same planse each time, but I'm never sure and curious to do so.

Thanks

Just call me a frequent flyer with too much time on the plane
