Depends on if you just want the room and some special compartments, or it you want a foam cut type setup so each can be held in its own spot.
Backpacks or hard cases are the 2 general options.
I use a backpack, purely for convenience to carry my setup where I want to fly from, often out bush.
Room for a light rain jacket, lunch, water, and the whole kit . . . M1P, 6 batteries, controller, filters, other misc items . . . GoPro session 5, power banks, cables, goodness knows what else is in there, lol.
I would take my DJI Pocket in the either a pants pocket for easy access, or in the shoulder strap pocket designed for a mobile phone.
I'm using the LowePro Droneguard BP250, they have smaller packs that would suit the
Air 2 with same or less gear.

Maybe the BP200 would suit the Air range, compartments are tailorable in most of these.
The best things besides ample room, is protection for the ipad mini4, and hardshell back where the drone and gear go.
For my Spark, I used a cheap school type backpack from kmart I think it was, $15.
Grey colour, has a nice big flat bottom for stability when putting it down.
I just leave the Spark in it's charging station, and controller / knick knacks in an old shaving zip up bag.
