Nuna PIPA RX: Airline & Country Compatibility
3.4 kg
44.5 cm wide
Infant FAA, CMVSS
The PIPA RX is Nuna's mid-range infant seat at 3.4 kg for the carrier. FAA-approved and installs without a base on aircraft, which is key for flying families. The European belt path makes it work internationally too. Lighter than most competitors in its class, with Nuna's signature merino wool blend fabrics and flame-retardant-free construction.

Traveling with the Nuna PIPA RX
Getting through the airport
At 3.4 kg for the carrier, the PIPA RX is one of the lighter infant seats you can fly with. It pairs with Nuna strollers (especially the TRVL) for a slick airport travel system. The carrier is comfortable to hand-carry for short distances, and the canopy provides decent sun coverage during outdoor gate waits. The magnetic buckle holders keep the harness out of the way when loading your baby in.
Using it on board
The PIPA RX is FAA-approved and installs baseless using the aircraft lap belt. At 44.5 cm wide, it fits standard economy seats. Nuna includes a European belt path, so it works in cars overseas without an adapter. Installation is straightforward if you practice once at home. The carrier sits level on most airplane seats without needing a rolled towel for adjustment.
Good to know
Nuna does not authorize Amazon sales, so buy from Nordstrom, Pottery Barn Kids, or the Nuna website to get the full warranty. The PIPA RX sits between the budget PIPA urbn and the premium PIPA Lite RX in Nuna s lineup. It offers the best balance of weight, features, and price for most traveling families. The RELX base with load leg is excellent for cars but stays home when you fly.
