Will the Mountain Buggy nano urban Fit in the Overhead Bin?
What Mountain Buggy says: Mountain Buggy says the nano urban fits most carry-on luggage limits on planes and trains.
Folded, the Mountain Buggy nano urban measures 21 x 20 x 12 in. That is bigger than a standard 22 x 14 x 9 in US carry-on in at least one direction, so it depends on the airline and on bin space.
| Airline cabin rule for strollers | Mountain Buggy nano urban on the maker’s numbers |
|---|---|
| United: 22 x 14 x 9 in | Over the limit |
| JetBlue: 22 x 14 x 9 in | Over the limit |
| Qantas: 22 x 14 x 9 in, 7 kg | Over the limit |
| Lufthansa: 55 x 40 x 23 cm | Over the limit |
| Air France: 55 x 45 x 25 cm | Over the limit |
| KLM: 55 x 45 x 25 cm, 10 kg | Over the limit |
| Spirit: 22 x 18 x 10 in | Over the limit |
| Singapore: 115 cm total, 7 kg | Over the limit |
| American: under 20 lb, must fit the bin | Under the weight limit |
Cabin space is first come, first served on most airlines, and the crew has the final say. Most airlines check a stroller free, at the gate or the counter; see airline stroller policies.

What Owners and Testers Report
- On the earlier nano, reviewers found the basket hard to load because of the low back and bar across the top (babygearlab.com)
- Earlier nano praised for maneuverability and compact fold but seen as best on smooth city pavement (babygearlab.com)
Mountain Buggy nano urban Alternatives
- Joolz Aer2: The Aer2 lies fully flat from birth, folds with one hand, weighs 14.3 lb and carries a 17.6 lb basket. No other stroller here combines all four.
- Silver Cross Jet 5: The Jet 5 lies flat from birth and folds onto two wheels so you can pull it like a suitcase. It is long when folded, though, and its basket is small.
