When I pack for a photography trip, other than my camera, my MacBook Pro is my next important item that I bring with me. My laptop was purchased in 2018 but if you purchased your 15-inch Macbook Pro between September 2015 and February 2017, your laptop might be impacted by a battery recall and until replaced, a new FAA ban could have your laptop grounded and unable to fly.
According to Apple, the issue affects the 15-inch MacBook Pro models with Retina displays. These laptops were shipped with batteries that “may overheat and pose a safety risk.”
This restriction covers both carry-on and hold luggage. My suggestion would be returning your computer to Apple for the free battery replacement. Otherwise, don't bother traveling with one to a U.S. airport.
If you're wondering if your laptop is one of the 458,000 units sold in the US and Canada that could be affected, head to the Apple support site and check the serial number. The replacement is pretty inconvenient, and can take as long as two weeks.
The European Union Aviation Safety Agency banned the laptops in early August, which has been implemented so far by Air Italy, Thomas Cook Airlines, Air Transat, and TUI Group Airlines. Domestic airlines in the U.S. are now following suit.
Although this ban is making headlines, the ban has been in effect since the recall notice was issued. This is most likely a result of people not taking the recall notice seriously.
