In June, Apple announced a recall for certain 15-inch MacBook Pro models that were sold between mid-2015 and 2017 on the grounds that their batteries could pose a fire risk. Now, for the same reason, the FAA is banning these models from flights in the U.S., according to a statement shared with Bloomberg.

You can (and should) check to see if your MacBook Pro is affected by checking its serial number on Apple’s website. If it is, you can (and should) send it in or take it to an Apple store for a free battery replacement, though that process may take as long as two weeks.

For the time being, we don’t know exactly how the ban will be enforced in U.S. airports. The problem is with the batteries, not the MacBook Pros themselves, so MacBook Pros with replaced batteries should be safe to fly. Still, it’s easy to imagine how strict, better-safe-than-sorry enforcement of the restriction could result in a de facto ban of repaired models, and potentially unaffected models as well. In short, it’s probably best to not fly with your 15-inch MacBook Pro for the forseeable future, if you can avoid it.
