We love our MB Nano. It’s challenging the first time to get it to close but after that it’s pretty easy to open, close and place in the bag for the overhead bin. https://amzn.to/3FHB7DV
I second the GB Pockit+ All City. The BEST travel stroller ever. I love mine.
Last time I flew, I brought the babyzen yoyo! Pretty light and it fits overhead!
