Can You Use a Booster Seat on an Airplane?
The short answer is yes, but with important caveats. The Federal Aviation Administration (FAA) recommends that children under 40 pounds use an approved child restraint system (CRS) on airplanes, but booster seats are generally not approved for use during taxi, takeoff, and landing. This is because booster seats rely on the vehicle's seat belt system, which is different from airplane lap belts. Most airlines allow booster seats to be used on board only if they are FAA-approved and have a label indicating they are certified for aircraft use.
However, many airlines permit the use of inflatable booster seats, like the BubbleBum Inflatable Car Booster Seat- Travel Car Seat- Black Twin Pack, because they are lightweight and can be deflated for storage. Always check with your specific airline before flying, as policies can differ. For example, some airlines may require the booster seat to be placed in a window seat to avoid blocking the aisle.
- Always check the airline's policy on child restraint systems before booking.
- Look for a label that says 'This restraint is certified for use in motor vehicles and aircraft.'
- Inflatable booster seats are often more accepted due to their compact size.
FAA Rules for Booster Seats on Planes
The FAA has specific guidelines for child restraint systems on aircraft. For children under 2 years old, the FAA strongly recommends using an approved CRS rather than holding the child on your lap. For children over 2, booster seats can be used if they meet certain criteria. The booster seat must have a label indicating it is approved for use on aircraft, and it must fit properly in the airplane seat. Most standard booster seats are too wide or bulky for airplane seats, which is why inflatable options are a popular choice.
The BubbleBum Inflatable Car Booster Seat - Travel Car Seat - Pink is a great example of a booster that meets FAA standards. It inflates to the correct height and uses the airplane's lap belt to secure the child, making it a safe and convenient option. Remember that the booster seat cannot be used during taxi, takeoff, and landing if it is not FAA-approved, so you may need to store it in the overhead bin during those phases.
- FAA-approved boosters must have a specific label and fit within the airplane seat dimensions.
- Inflatable boosters are easier to store and often comply with airline size restrictions.
- Always secure the booster seat with the airplane lap belt, not the shoulder belt.

How to Install a Booster Seat on an Airplane
Installing a booster seat on an airplane is different from installing it in a car. First, place the booster seat on the airplane seat and ensure it is level. For inflatable boosters, inflate the seat to the recommended firmness. Then, thread the airplane's lap belt through the designated belt path on the booster seat and buckle it securely. Make sure the belt is tight and the seat does not move more than an inch in any direction.
For the BubbleBum Inflatable Car Booster Seat- Travel Car Seat- Black, the installation process is straightforward. The seat has a built-in belt guide that helps position the lap belt correctly. After installation, double-check that the child's knees bend comfortably over the edge of the seat and that the lap belt sits low on the hips, not on the stomach. If the child is too small, you may need to use a forward-facing car seat instead of a booster.
- Inflate the booster seat to the recommended level before installing.
- Ensure the lap belt is snug and the seat is stable.
- Practice installation at home before your trip to save time at the airport.
Alternatives to Using a Booster Seat on a Plane
If your child is under 2 years old or if the airline does not allow booster seats, consider other options. One alternative is to use a CARES (Child Aviation Restraint System) harness, which is an FAA-approved device that attaches to the airplane seat. Another option is to book a separate seat for your child and use a forward-facing car seat that is FAA-approved. For older children, the airplane's lap belt alone may suffice, but it's important to ensure the child is tall enough to sit with their back against the seat and knees bent.
For families who want a versatile solution, the BubbleBum Teleport Backless Booster Car Seat is a great choice for both car and air travel. It is compact and easy to carry, and it can be used as a backless booster in the car. However, on the plane, it may not be allowed during takeoff and landing, so you'll need to store it. Always have a backup plan, such as a travel activity book or snacks, to keep your child entertained during the flight.
