Joie Mint Latch Infant Car Seat: Flying-Family Review

Per Joie's product documentation, the Mint Latch is FAA-certified for aircraft use under FMVSS 213. All US-market infant seats must carry a red FAA certification sticker stating the seat is certified for use in motor vehicles and aircraft — the Mint Latch carries this label on the carrier shell. Before boarding, parents should verify the red certification sticker is present and legible, as gate agents may check it. On the aircraft, the carrier is installed using the airplane's two-point lap belt only — the built-in rigid lower anchor connectors are not used in flight because aircraft seats do not have lower anchors. Always check the sticker before each flight to avoid boarding delays.

The Joie Mint Latch's defining feature is its rigid lower anchor connectors built directly into the carrier shell, eliminating the need for a separate base for LATCH installation. Most infant seats require a separate base that must be installed in the vehicle first, then the carrier clicks into the base. The Mint Latch skips the base entirely — the carrier clicks directly into the vehicle's lower anchor hardware the way a convertible seat does. For rideshare-heavy families who use Uber and Lyft frequently, this means a 10–15 second LATCH install with no base to manage in the back seat of a stranger's car. For flight travel, the baseless design means there is no separate base to gate-check.

Per Joie's published specifications, the Mint Latch is rated for infants from 4 lbs to 30 lbs in rear-facing-only mode, with a standing height limit of 30 inches. There is no forward-facing weight limit because the Mint Latch is an infant-only seat — once your child exceeds 30 lbs or 30 inches, whichever comes first, they must transition to a convertible or all-in-one seat. The 30-lb ceiling is lower than most infant-mid competitors such as the Chicco KeyFit 35 (35 lbs) and UPPAbaby MESA V2 (35 lbs). Families who anticipate keeping a child in an infant seat beyond 12–15 months should consider whether the Mint Latch's shorter window suits their plans. Always weigh your child on a recent doctor-visit scale rather than estimating.

Yes — and this is the Mint Latch's strongest use case. The rigid lower anchor connectors are built directly into the carrier, so the carrier clicks into the rideshare vehicle's lower anchor hardware with no separate base required. The install takes approximately 10–15 seconds once you locate the lower anchors, which are typically visible at the junction of the seat back and seat cushion in LATCH-equipped vehicles (all US vehicles manufactured from 2002 onward). If the lower anchors are not accessible — sometimes they are buried deeply in a tight seat crease — the lap-belt-only install is the backup. Per CPST guidance, always verify the carrier does not move more than one inch side-to-side or forward at the belt path after installation.

Per the Mint Latch's published specifications, the carrier measures 17.75 inches at its widest point. This width fits Spirit Main Cabin (approximately 17.75 in), Southwest 737 MAX 8 (17.8 in), JetBlue A321 (17.8 in), Delta A321neo (17.2 in), and United 787-9 economy (17.3 in) with armrests in the down position. American Airlines 737 Main Cabin rows (approximately 16.7 in) require armrests raised on both sides of the seat to accommodate the carrier. Most US carriers permit armrests to be raised for child-restraint installation. Rear-facing infant carriers in general require 31 inches or more of seat pitch — bulkhead rows or premium economy are strongly recommended for rear-facing installs.

Per NHTSA's public recall database and CPSC's recall search, the Joie Mint Latch has no recall campaigns on file as of May 2026. Joie is part of the Britax family of brands and has a long-standing safety track record in both the European and US markets. To monitor for future recalls, parents can register their seat with Joie at joiebaby.com and sign up for NHTSA email alerts at nhtsa.gov/recalls. Always include the manufacture date, model name, and purchase date on any warranty or recall registration for accurate recall tracking.

Per standard Joie guidance, the Mint Latch expires six years from the date of manufacture. The date of manufacture is stamped on a label on the underside of the carrier shell — parents should locate this label before reusing the carrier for a second child. Once expired, the seat should not be reused or resold; plastic and foam materials degrade over time and may not perform as intended in a crash. Because the Mint Latch has no separate base, there is only one expiration label to check rather than the two labels found on carrier-plus-base systems. Recycling programs at Target and Walmart accept expired car seats for material reclamation during periodic car-seat trade-in events.

The Joie Mint Latch and Chicco KeyFit 35 are both infant-mid cluster seats with FAA certification and similar carrier weights (Mint Latch 9.3 lbs; KeyFit 35 approximately 9.6 lbs). The Mint Latch's standout advantage is its built-in rigid lower anchors — no base required for LATCH installation, making rideshare and rental-car installs dramatically faster. The KeyFit 35's advantages are a longer rear-facing window (35 lbs, 32 in vs the Mint Latch's 30 lbs, 30 in), SuperCinch LATCH tensioner with base-included install, and a lower street price of approximately $199–249 versus the Mint Latch's $299. For frequent rideshare users, the Mint Latch's convenience premium is worth it; for families who drive primarily in one car with a permanently installed base, the KeyFit 35 is the more economical and longer-lasting choice.

Per CPST community guidance, the most common install error for baseless rigid-LATCH infant seats is failing to verify the recline angle after each new install. Because there is no adjustable base, the carrier's recline is set by the vehicle seat geometry — which varies significantly between a Honda Odyssey second row and an Uber driver's sedan. Always check the recline indicator on the carrier after every new install. The second most common error is engaging the rigid lower anchors during an aircraft install — the rigid anchors must not be used on airplanes per FAA AC 120-87C. Use only the aircraft's lap belt. The third most common error is leaving the chest clip at belly level instead of armpit level, especially after adjusting harness height as the baby grows.
