Apple's push towards Bluetooth headphones introduces an inconvenience I hadn't considered until flying today. When preparing for takeoff, I put my phone in airplane mode, like a law abiding citizen should, and BAM! No headphone audio. Because of the way iOS handles Airplane Mode, Bluetooth and wifi are cut off, along with the cellular radio. Obviously I just paired my headphones again, but it's unfortunate that Apple's definition of Airplane Mode is based on outdated rules. I'd like to see Airplane Mode modernized to only cut off cellular, or better yet, be customizable to allow unique definitions of what "Airplane Mode" is (as laws vary by country). I submitted this feedback to Apple, I'll share if I hear anything.
