Peg Perego - Veloce

Of the options you listed, the Cruz V3 will easily be the best for going over rough ground, but the same elements that make it so great in that respect also make it the largest and heaviest (26 lbs, I think) - you likely won't be able to gate check it. Unfortunately, the lightest/most compact strollers tend to have little/no suspension and smaller wheels as a consequence, so you may have to decide which feature you think is more important. Aer2 and Minu v3 apparently have good suspension and relatively large wheels for their class (i.e., ultracompacts), but will still have the most trouble going over rough ground. Hub2 is somewhere in the middle, although the suspension is a little firm and I don't love the fold (I think you have to reverse the seat first, and the seat removal wasn't super intuitive to me.) An important question here is whether you want baby to be able to face you while you push. If so, that automatically eliminates Aer2 and Minu (and almost every other compact stroller). Some other lighter reversible-seat strollers that still have decently sized wheels are the Nuna Triv Next, Bugaboo Dragonfly, and Peg Perego Veloce. Cybex has the Mios, but the wheels are much smaller (so it will have a tougher time around rough terrain). The Dragonfly is very tall when folded though (even taller than the Cruz), so it may not work that well if your trunk space is limited. If you don't care about a reversible seat, the Nuna TRVL/TRVL LX, Cybex Beezy (latest model), Uppababy Minu v2, Peg Perego Selfie Plus, and Guzzie and Guss Oxygen v2 are all lighter than 20 lbs, have a one-hand fold, and have larger wheels and more substantial suspension than the Aer2/Minu v3 (or any other ultracompacts, for that matter).

Highly recommend the Peg Perego Veloce stroller for the amazing one-handed fold. Definitely a bit pricier, but is often on sale for $800. Suspension and wheels are also great for city living!
