Its so frustrating that every apple device has a netflix app, but Macs do not. Before people scream "just use the internet," I fly a lot for work, and you cannot use the internet in airplane mode. My iPhone, as well as my windows PC, has the app, where you can download a movie/show to watch while offline.
I don't like watching media on my IPhone during flights, because the battery drains too quick, which means I have to take my large and heavy laptop with me on flights. Its annoying, and seems unnecessary.
I travel on planes a lot, and since I don't have an iPad, I have to bring my laptop in my carry-on simply stream Netflix, which is highly annoying. Sure, I can use my iPhone, but the screen is small and I'd rather not waste the battery.
Travel would be a lot easier if my Mac can do what every other device can do, which is download a movie from Netflix, and then watch on Airplane Mode
