- Applies to every car: private car service, taxi, ride-sharing services, hotel shuttle, and rental car.
- SNA is family-friendly: look for family screening lanes, wide elevators, and short walks.
- Baby food is allowed: formula, milk, and purées over 3.4 oz are OK when you declare them at security.
- Plan time on the road: San Diego → SNA is ~86–87 miles. Add buffers for Del Mar, Carlsbad, San Clemente, and the El Toro Y.
- Keep it simple: pack a stroller you can fold fast, and a small “gate bag” for the car seat.

Choosing the Right Car Seat by Age, Height, and Weight
Child size | Seat to use | How to check fit | Common mistakes to avoid |
Babies and small toddlers | Rear-facing convertible or infant seat | Harness at or below shoulders; head at least 1 inch below shell | Installing too upright; straps too loose |
Preschoolers | Forward-facing with harness | Harness at or above shoulders; chest clip at armpit level | Switching to booster too soon |
Grade-schoolers | High-back or backless booster | Seat belt crosses shoulder and hips, not neck or tummy | Tucking belt under arm or behind back |
Bigger kids | Vehicle seat belt | “Five-step test” passes; knees bend at seat edge | Belt on belly; slouching |
Safety tip: Rear-facing as long as the seat allows. Harness as long as your child fits.

What Families Can Expect at SNA
- Family screening lanes: look for signs near the main checkpoints. Ask a TSA officer if unsure.
