What a Infant needs to Travel !

 Tip #1 

• A ticket, in some cases. Most airlines don’t require you to buy a ticket for babies younger than 2 years old for domestic flights, but she’ll have to sit on your lap, and taxes and fees may still apply. If you do purchase a ticket for a separate seat, she’ll need to sit in her car seat (more on that later). Flying internationally? Your under-2-year-old may need her own ticket depending on the airline. In either case, if you don’t need a ticket for your baby, you still need to notify the airline that you’re bringing her on the plane. As for kids 2 and up? They always need a ticket.   
• Tip #2
• A passport for international flights. All U.S. citizens, including newborns, need their own passports to fly internationally. To obtain one for your baby, you’ll need to use the DS-11 form and apply together in person, so plan ahead. For domestic flights, babies and children under 18 don’t need a passport or an ID. 
• Tip #3 

• Her birth certificate. Some airlines require proof of age documentation for babies and children under 18. Call ahead to find out if you need it, or to be safe, just bring it along.
• Tip #4

• A letter of consent to travel. For international travel, unless a baby or child is traveling with both parents, U.S. Customs and Border Protection strongly recommends having a notarized letter granting parental permission. If the child is traveling with one parent, the other parent should authorize the note. If the child is traveling without either parent, both parents should authorize the note. 

Tip #5

• A face mask, for toddlers 2 and up. To protect against COVID-19, commercial air passengers over age 2 must wear a face mask throughout the duration of their travel experience, says the Transportation Security Administration (TSA).
