Know Before You Go
- A child can travel as a lap infant from 3 days old until the day they turn 2 years old. There’s no charge for lap infants (taxes may be due outside the U.S.) but you will be asked for proof of age, such as a birth certificate, passport or immunization record.
- If you’re traveling with a lap infant, you can bring aboard a diaper bag in addition to your carry-on and personal item.
- Our Blue Basic fares do not include free advance seat selection, so if you’re traveling with kids and want to be sure to sit together, we recommend booking another fare. Blue, Blue Plus and Blue Extra all include free advance seat selection.
- Strollers and car seats do not count toward your carry-on or checked bag allowance. You may check them through when you arrive at the airport or gate-check them at the jetbridge.
- A car seat is not required for an infant or child in their own seat, as long as they can sit upright unassisted. You may use your FAA-approved safety seat on board, as long as you’ve purchased a seat or there's a suitable vacant one available.
- Breast pumps are considered an assistive device and do not count toward your two allotted carry-on bags.
- If your child is traveling internationally with only one parent (or another adult), you may need a minor travel consent form.
- Children 5-14 years may travel as unaccompanied minors. Review full details and form.
- There is no age minimum to sign up for a TrueBlue account and earn points toward award travel on JetBlue.
