I owned all three at one point. My first drone was the Mavic Air, then the Mavic Mini came out and I purchased that and most recently I purchased the
Mavic Air 2.
You're asking as a first time drone owner/pilot between the Mavic Air and the Mavic Mini, I'd go with the Mavic Mini, it's just so much fun to fly and very simple once you get the hang of it, it has some great features and as long as you fly responsible and pay attention to the weather conditions you'll be very happy with it! And as mentioned above, much better battery life. Buy the Fly more combo if you can afford it.
The Mavic Air is a bit more capable but also a bit more intimidating I feel for new pilots. I wish the MM was my first drone but unfortunately it was not out yet so I went with the Mavic Air but when the MM came out I bought it for the fun factor and to fine tun my close up skills. Overall I REALLY like my MM, I use it a lot, it's just so fun & simple.
One BIG thing to note is the
MA is a bit louder with a unique there's a drone above you sound lol, the MM is definitely quieter.
Also as noted above, the
MA2 is an amazing drone and my favorite especially now that it's compatible with the
smart controller.
BUT... To answer your question... Mavic Mini 100%.... If looking to learn and get used to things, want some great pics & vids, a super portable/easy to travel with package, great batter life, and again just a super fun drone to fly! I'd think you'd be happy with that choice. It's very capable with some great features! In a year or so if you're still into the hobby, you sell it and upgrade like most of us do.
Good Luck and let us know what you go with!
