Bugaboo Butterfly 2 Plus vs Stokke YOYO³
Both are pitched at parents who fly often, and they are $80 apart: the Butterfly 2 Plus is $579 and the YOYO³ $499. The YOYO³ is lighter at 14.8 lb against 16 lb and misses the carry-on box by 3.3 inches against the Butterfly's 3.6, so on paper they are a coin toss. Owners say the Butterfly goes into overhead bins on Emirates, BA, EasyJet and Delta, though crews have sent it to the gate on full flights. The difference that matters is the baby's age. The Butterfly seat is suitable from birth, with a foot cover, a 17.6 lb basket and adapters for Turtle, Pipa, Maxi-Cosi, Cybex and Clek Liing seats. The YOYO³ 6+ seat starts at 6 months; younger babies need the YOYO 0+ newborn pack or a car seat on YOYO³ adapters. Under 6 months, the Butterfly costs less than it looks, because those extras eat the YOYO³'s $80 saving. Past 6 months, the YOYO³ is lighter, cheaper and a shade closer to carry-on size, and the Butterfly's newborn features stop mattering.
Folded, the Stokke YOYO³ makes a 1.46 cu ft box to the Bugaboo Butterfly 2 Plus's 2.13 cu ft. Neither fits a 22 x 14 x 9 in carry-on sizer: the Bugaboo Butterfly 2 Plus misses by 3.6 in and the Stokke YOYO³ by 3.3 in. The Stokke YOYO³ is 1.2 lb lighter by its maker's figure (14.8 lb to 16 lb). The Bugaboo Butterfly 2 Plus is newborn-ready as sold; the Stokke YOYO³ needs a bassinet, insert or infant car seat for the first months.

Bugaboo Butterfly 2 Plus: what it gives up
- Folded, it is 3.6 inches over a carry-on box's 14-inch side; owners usually get it into the bin anyway, but crews sometimes make them gate-check it
- Fixed 40.3-inch handlebar with no adjustment
- Bugaboo's own spec table still recommends a car seat for newborns
- Owners report the car-seat adapters get stuck if fitted on the wrong sides
Stokke YOYO³: what it gives up
- 17.3-inch folded width is over a 14-inch carry-on limit
- 6+ seat only from six months; newborn pack and adapters cost extra
- Stokke prints two different weights on the same page
- Without a stated child limit, you cannot plan when a toddler outgrows it
