Questions parents ask

Which is better for naps?

Butterfly 2 is the stronger nap choice. Its seat, leg support, canopy, and suspension create a more comfortable setup for an on-the-go nap. Neither stroller seat should be treated as an unsupervised sleep space.

Which stroller is easier to take on a flight?

Both are marketed around IATA-size travel, but airlines and aircraft cabin space make the final decision. Aer2 has the advantage when you need the lighter stroller to lift into a car, train, or overhead bin.

Which has the better basket?

They list the same 17.6 lb capacity. Butterfly 2 is easier to use with a typical day bag because its opening is wider, while Aer2 is more constrained with bulkier bags.

Can either replace a full-size stroller?

Butterfly 2 is the more convincing compact main-stroller option for city families. Aer2 can work as a light city main stroller when routes are smooth and you prioritize carrying weight over storage and suspension.
