MacBook Air 15

According to Apple's Technical Specifications, the 15" M3 MacBook Air weighs "3.3 pounds (1.51 kg)". There is a footnote that "Weight varies by configuration and manufacturing process."

The now-discontinued 15" M2 MacBook Air weighs the same, with the same footnote. There weren't any 15" M1 MacBook Airs.

I assume these weights are for the notebook only, and do not include the power adapter and charging cord, should you choose to carry those around with you.
