We have several airline-compatible buggies in our range.
The Bugaboo Butterfly, a travel buggy with spring suspension https://strollme.de/produkt/bugaboo-butterfly/
the Yoyo. particularly small and handy https://strollme.de/produkt/yoyo/
or the Miley, where you can set the backrest very flat. Perfect if your child likes to sleep in the pushchair https://strollme.de/produkt/easywalker-miley/
All three are approved for hand luggage. However, each airline has its own regulations for cabin baggage.
We therefore recommend that you check with the airline before your flight.
We have put together a comparison of travel buggies for you here:
