I've had mine for less than a week now. I bring it EVERYWHERE. It packs really small and the case it comes with is sturdy as can be. You may want to get a case for the controller, but that's probably it if you want to pack small. Mine fits nicely in my backpack, I took it snowboarding at Loveland PAss yesterday (backcountry) and filmed a bit in the snow. I'd recommend buying a landing pad too if you're not taking off/landing from concrete. I bought a weighted one for $40 from my local DJI shop that is very nice, although it's probably as heavy as the drone.
This *is* the drone you want. The flying time is much longer than you'd realize. I'd personally recommend skipping the fly more combo and just get the drone and some extra batteries, and a fast microSD card from Amazon.
The GPS and "Return to Home" make this a very safe drone to fly. You can fly to some pretty crazy places, and just press the "return to home" button when you're ready for it to come back.
TL/DR: Get yourself a Mavic Air, you're going to freaking love it, and you're going to take it everywhere you go.
