In June, Apple recalled the 2015 MacBook Pro with Retina display - sold between September 2015 and February 2017 - because of suspicions that the battery "could pose a safety risk" for its combustibility.

But some airlines have banned all models of Apple's Mac computers, whether they have a bad battery or not, according to Bloomberg news site.

Australian Virgin
The company doesn't want to take any risk. It bans carrying all MacBooks with charged bags. Virgin has placed all MacBook models on the Dangerous Goods page, regardless of whether they are called by Apple. The law is clear, and all Apple computers can only be brought in suitcases inside the cabin.

Australian Qantas
If you fly on that company with a 15-inch MacBook Pro, it requires all passengers to carry the device with them inside the passenger compartment and force them not to use it while flying.

A Qantas spokesman told ZDNet: Until further notice, all Apple MacBook Pro devices must be carried with the passenger inside the cabin and shut down throughout the flight.

Thai and Singapore Airlines
Both Singapore and Thai Airlines also announced a complete ban on the affected devices, and the affected models were blocked from both the cabin and luggage charging unless it was verified that the battery had been replaced.

American domestic flights
The Federal Aviation Administration of the United States responded to the ban, banning affected MacBooks from all baggage, whether in the cabin or with luggage.

The difficulty for airline and airport staff is how to identify the affected models. All 15-inch Mac Pro models look similar, so security personnel are not expected to know about all excluded models.

Airlines and customers alike can check whether their MacBook Pro is within the recalled devices through the Apple Support page.
