Joolz Aer+ and Bugaboo Butterfly 2 pose a practical choice: how much weight you want to carry and which configuration your child needs. Aer+ has the lower stated stroller weight; Butterfly 2 documents greater basket capacity. This comparison concerns Aer+ and Butterfly 2, not Aer2 or the original Butterfly.
Figures come from the specified listings; we have not conducted a joint hands-on test.

Carrying weight versus shopping space
The stated weight difference is 1.3 kg in the Aer+’s favour. That may matter if you regularly use stairs, but does not by itself establish which feels easier to lift. Try the grip and carrying strap too. Butterfly 2 permits a higher stated basket load; that limit does not add to seat capacity or permit hanging weight from the handlebar.
Your child’s configuration changes the comparison
The Spanish listing’s 6 kg refers to the stroller, not a complete cot package. Its US listing specifies that the seat is for children who can sit unaided, usually around six months. Do not use the stroller-only weight to assess a cot package. The UK Butterfly 2 listing states use from birth; confirm the permitted configuration in the exact unit’s manual and purchase market.
An independent experience with limits
Laura Westerman tested Butterfly 2 for a month with her three-year-old daughter for Mumsnet. She describes daily use and trips but explicitly says she did not fly with it. Her experience provides context for that unit and age; it does not establish universal cabin acceptance or superiority over Aer+.
Travel, markets and packages
Check your unit’s dimensions against your airline’s conditions: carry-on marketing does not guarantee admission on every aircraft. For Spain or the United States, consult the local listing, warranty and exact manual. An offer labelled only “Aer” or “Butterfly” may belong to another generation.
Compare package contents too: cot, adapters, footrest and rain cover should not be assumed included without checking the offer. We have not verified exact Amazon listings, prices or stock. Choose Aer+ if stroller weight is your priority and its configuration fits; consider Butterfly 2 if you will use the greater basket capacity. For a newborn system, establish the permitted configuration first, then compare complete weight and cost.
