The flight attendants will have to start checking that you have a wire to your headphones more than they do now.
For those that buy the iPhone 7, you're out of luck for listening while flying, unless there is an adapter.
I was considering getting the last one with a headphone jack and trying to wait it out until the jack is returned.
Maybe I'll have to go Android to get the usage model I want. I fly weekly, and noise cancelling headphones are my standard attire, they require a jack.
