- US carriers: lap infant under 24 months, free domestically.
- International: usually 10% of fare plus taxes.
- Add the infant during booking (not after) to ensure correct ticketing.
At the airport
- Bring the birth certificate or passport for international travel.
- Stroller and car seat fly free as gate-checked items.
- Use family security lanes when available.
Onboard
