1. Cosco Scenera NEXT: Best Overall for Air Travel
The Cosco Scenera NEXT is a top pick for air travel due to its lightweight design and FAA approval. At just 7.5 pounds and 17.5 inches wide, it fits easily into most airplane seats and is simple to carry through terminals. Owner feedback highlights its straightforward installation and no-rethread harness, making it a favorite among frequent flyers.
However, the seat has minimal padding, which might reduce comfort on longer flights. Families with toddlers who need extra cushioning may want to consider a more padded option. It also lacks a cup holder, a minor inconvenience for some. Overall, it is an excellent choice for budget-conscious travelers prioritizing weight and ease of use.
- Lightweight at 7.5 lbs makes it easy to carry through airports
- Narrow 17.5 inch width fits most airplane seats without armrest issues
- Simple harness adjustment with no rethread required
Pros: Extremely lightweight and compact; Budget-friendly without sacrificing safety
Cons: Limited padding may be less comfortable for long flights; Harness straps can twist easily
2. Evenflo EveryStage DLX: Best All-in-One for Air Travel
The Evenflo EveryStage DLX is a versatile all-in-one seat that transitions from rear-facing to booster. It is FAA approved for airplane use, but its 21-pound weight makes it one of the heavier options for carry-on. Owner reviews praise the SensorSafe chest clip that provides alerts, and the easy LATCH installation is a plus for car use.
For air travel, the bulk and weight are significant drawbacks. It may be too wide for some airplane seats, and carrying it through the airport can be cumbersome. This seat is best for families who need a long-lasting seat for the car and are willing to deal with the extra weight on occasional flights.
- Grows with child from infant to booster seat
- SensorSafe chest clip alerts if child unbuckles or temperature changes
- Quick and easy LATCH installation with push-on connectors
Pros: Long lifespan with high weight limits; SensorSafe technology adds safety monitoring
Cons: Heavy at 21 lbs, less ideal for air travel; Wider base may not fit all airplane seats
3. Graco Extend2Fit: Best Extended Rear-Facing for Travel
The Graco Extend2Fit is popular for its extended rear-facing capability up to 50 pounds, which is a safety advantage. It is FAA approved, but its 19-pound weight and larger footprint make it less convenient for flying. Owner feedback notes that the no-rethread harness and multiple recline positions are great for car use.
For airplane travel, the seat’s bulk can be problematic. It may not fit well in smaller seats, and carrying it through the airport is tiring. Families who prioritize extended rear-facing and primarily use the seat in the car may still consider it for occasional flights, but lighter options are better.
- Extended rear-facing up to 50 lbs with panel extension
- No-rethread harness and 10 position headrest
- Steel-reinforced frame for durability
Pros: Allows longer rear-facing for safety; Easy harness adjustment without rethreading
Cons: Heavy for air travel at 19 lbs; Bulky design may not fit narrow airplane seats
4. Chicco NextFit Zip: Best Premium Comfort for Air Travel
The Chicco NextFit Zip offers premium comfort with memory foam and multiple recline positions. It is FAA approved, but its 20-pound weight and larger size make it less travel-friendly. Owners appreciate the SuperCinch LATCH system for easy installation in cars and the zip-off cover for hassle-free cleaning.
For air travel, the seat’s weight and bulk are significant drawbacks. It may not be practical for families who fly frequently or need to carry the seat through large airports. This seat is better suited for those who prioritize comfort and are willing to manage the extra weight on occasional flights.
- Zip-off cover for easy cleaning without uninstalling
- SuperCinch LATCH tightener for secure installation
- Nine recline positions and memory foam padding
Pros: Plush padding for child comfort on long flights; Zip-off cover is convenient for cleaning
Cons: Heavy at 20 lbs, difficult to carry; Higher price point
5. Britax Marathon ClickTight: Best Safety Features for Air Travel
The Britax Marathon ClickTight is renowned for its safety features and easy ClickTight installation. It is FAA approved, but its 25-pound weight makes it one of the heaviest convertible seats for air travel. Owner feedback praises the secure installation and high safety standards, but many note the weight is a major drawback for flying.
This seat is not recommended for frequent flyers or those who need to carry the seat through airports. It is best for families who primarily use the seat in the car and only fly occasionally, as the weight and bulk can be a significant burden.
- ClickTight installation system for foolproof seat belt installation
- Steel frame and energy-absorbing foam for side impact protection
- Quick-adjust headrest and harness without rethread
Pros: Excellent safety ratings and side impact protection; ClickTight makes seat belt installation easy and secure
Cons: Very heavy at 25 lbs, worst for air travel; Bulky and may not fit in all airplane seats
6. Safety 1st Grow and Go All-in-One: Best Value All-in-One for Air Travel
The Safety 1st Grow and Go All-in-One is a budget-friendly option that is relatively lightweight at 17 pounds for an all-in-one seat. It is FAA approved and offers rear-facing, forward-facing, and booster modes. Owner reviews note that the harness adjustment is easy and the seat pad is machine washable.
However, the seat has minimal padding, which may be uncomfortable on longer flights. Some users also report difficulty with installation in certain vehicles. For air travel, it is a passable choice if you want a single seat for all stages, but there are lighter and more comfortable options available.
- 3-in-1 design grows with child from rear-facing to booster
- Quick-fit harness with 5 positions and no rethread
- Machine-washable seat pad
Pros: Lightweight for an all-in-one at 17 lbs; Budget-friendly with long lifespan
Cons: Less padding and comfort for long flights; Installation can be tricky in some cars
7. Maxi-Cosi Pria 85 Max: Best Narrow Fit for Airplane Seats
The Maxi-Cosi Pria 85 Max is designed with a narrow 17.5 inch width, making it a good fit for airplane seats. It is FAA approved and offers a high forward-facing weight limit of 85 pounds. Owner feedback highlights the easy-to-remove cover for cleaning and the AirProtect headrest for safety.
At 18 pounds, it is still relatively heavy for carrying through airports, but its narrow profile helps with installation on the plane. Some users find the harness adjuster difficult to tighten. This seat is a solid choice for families who need a narrow seat for air travel and are willing to accept a moderate weight.
- Narrow 17.5 inch width fits most airplane seats
- RapidRemove cover for easy cleaning without uninstalling
- AirProtect headrest with side impact protection
Pros: Narrow design fits well in airplane seats; Easy to clean cover
Cons: Heavier than some narrow options; Harness adjuster can be stiff
Frequently Asked Questions
Are all convertible car seats FAA approved for airplane use?
No, not all convertible car seats are FAA approved. Look for a label that states ‘This restraint is certified for use in motor vehicles and aircraft.’ The seats we reviewed are all FAA approved, but always check the manufacturer’s specifications before flying.
Can I use a convertible car seat on an airplane in rear-facing mode?
Yes, you can use a convertible car seat rear-facing on an airplane as long as it is FAA approved. However, the seat must fit within the airplane seat dimensions and the child must be within the weight and height limits for rear-facing use. Some airlines may have additional restrictions, so check with the airline beforehand.
How do I install a convertible car seat on an airplane?
Installation on an airplane is done using the airplane seat belt. Place the car seat on the airplane seat, route the lap belt through the correct belt path (usually marked), buckle it, and tighten until the seat is secure. Do not use LATCH on airplanes. The seat should not move more than one inch side to side at the belt path.
What is the best lightweight convertible car seat for air travel?
The Cosco Scenera NEXT is the lightest at 7.5 pounds and is a popular choice for air travel. Other lightweight options include the Safety 1st Grow and Go All-in-One at 17 pounds and the Maxi-Cosi Pria 85 Max at 18 pounds. Weight is a key factor for portability.
Can I check a convertible car seat as luggage instead of using it on the plane?
Yes, you can check a car seat as luggage, but it may get damaged in transit. It is safer to use it on the plane for your child if they have a seat. If you check it, consider using a protective travel bag. Note that checked car seats are not covered by airline damage policies.
