Flying with a newborn: step-by-step

Planning the trip? Use our milestone tracker to confirm baby is hitting age-appropriate developmental signs before traveling.

When is it safe to fly

Most pediatricians say:

• Healthy full-term babies: can fly after about 2 weeks. Most providers prefer to wait until 6 to 8 weeks (after the 2-month vaccines) if travel isn't urgent.
• Premature babies: wait longer. Talk to your pediatrician.
• NICU graduates: wait until your pediatrician clears you.
• Babies with respiratory issues (BPD, congenital lung issues): may need supplemental oxygen on flights or to avoid flying altogether.

Newborns are vulnerable to germs. The 2-month vaccine series provides some protection against pertussis, RSV (with the new infant immunization), and other infections that spread on planes. Waiting until after those vaccines is worth doing if you can.

Lap infant vs paid seat

Lap infant

Under 2 years old, your baby can fly in your lap. Free on domestic flights for most US airlines. $10 to $100+ on international flights (varies by airline and destination).

Pros: free, less logistics, easier to nurse and rock baby.

Cons: the AAP and FAA both recommend against it for safety reasons. In severe turbulence or accidents, an unrestrained infant is at risk. Statistically rare, but the risk exists.

Paid seat with car seat

Buy a seat for baby. Bring your car seat (FAA-approved; check the label). Install it in the seat.

Pros: safer in turbulence and accidents. Baby has their own space. You can put baby down to nap. Some babies sleep better in the car seat than your lap.

Cons: cost of the seat. Carrying a car seat through the airport.

AAP recommendation: buy the seat, use a car seat. Especially for longer flights.

What to pack in your carry-on

• 50% more diapers than you think you need. 1 per hour of total travel time plus 5 extra. Delays happen.
• Wipes (full pack). TSA allows these in carry-on.
• 2 to 3 changes of clothes for baby. Outfits will get destroyed. Pack ones easy to change in tight spaces (zip-front rompers).
• 1 change of clothes for yourself. Spit-up and blowouts will happen on you too.
• Burp cloths (3 to 5).
• Bottles or breastfeeding supplies. TSA allows breast milk, formula, and water for formula in carry-on without quantity limits (declare at security).
• Pacifiers (2 to 3, in case one falls).
• Soft swaddle blanket. Doubles as nursing cover, sun block, floor mat.
• Small toy or teether. Doesn't need to be much for a newborn.
• Baby Tylenol (infant version) if your pediatrician okayed for travel.
• Hand sanitizer.
• Disinfectant wipes for tray tables, armrests, and window.
• Plastic bags for dirty diapers and soiled clothes.
• Pediatrician's contact info. Just in case.
• Insurance card and baby's birth certificate copy (international travel only requires passport).

What to pack in your checked bag

• The rest of the diapers for the trip (you can also buy at destination).
• Outfits and pajamas.
• A travel sound machine.
• Sleep sack if baby uses one.
• A portable changing pad.
• Anything else you'll need on the ground.

Don't pack: anything irreplaceable in checked luggage. Carry on prescription medications, formula, and breast milk.

Booking the flight

Pick the right time:

• Direct flights only if possible. Connections double everything: TSA, gate transit, takeoff/landing pressure.
• Off-peak times. Early morning or late evening flights are less crowded. Tuesday-Thursday tend to be quieter.
• Avoid holidays. Stressed-out passengers + sick passengers + delays.
• Time of day: some parents swear by night flights (baby sleeps); others prefer mid-morning (baby is fresh).

Seat selection:

• Window seat. Less foot traffic. Easier nursing privacy. Baby can lean against the window for naps.
• Bulkhead seats often have a bassinet hook (more on this below).
• Avoid emergency exit rows. Babies aren't allowed in them.
• Buy 2 adjacent seats if you can afford an extra. The third seat being empty (which often happens with strategic seat-choosing) is a luxury.

Bulkhead bassinets

Some international flights have bassinets that attach to the bulkhead wall. Limited (a few per flight), often booked early, only fit babies up to about 20 lbs / 6 months. Request when booking.

Getting through TSA

• Lap infants don't need a ticket or boarding pass on domestic flights, but most airlines require you to add them to the reservation.
• Domestic identification: baby's birth certificate or pediatrician's note. Some airlines accept just a verbal confirmation of age.
• International: baby needs a passport. Apply early; it can take 6 to 8 weeks.
• TSA Pre-Check: baby is included with parent. Worth signing up if you'll travel multiple times in baby's first 2 years.
• Strollers and car seats fly free. Gate-check both.
• Carry baby through the X-ray, not in the stroller. The stroller goes through separately.
• Don't take baby out of the carrier unless TSA explicitly asks. They usually don't.
• Formula, breast milk, and water for formula are allowed in any quantity. Declare to TSA before screening. They may run them through additional screening.

Boarding and the flight itself

Boarding strategy

Two schools of thought:

• Pre-board: get on first, settle in, breastfeed before takeoff, baby is calmer.
• Last-on: get on last, minimize time on the plane (baby's max patience window). Send your partner on first with the bags; you walk on at the final call.

For solo flying, pre-boarding is usually easier. For two adults, last-on works if one of you can stow the bags.

Takeoff and landing

Babies' ears hurt during pressure changes. Sucking helps clear the eustachian tubes.

• Feed at takeoff. Breast or bottle. Time it so the bottle is going in as the plane starts rolling. If breastfeeding, start nursing as the plane pulls back from the gate (you may need to release latch and re-latch for takeoff itself).
• Feed at landing. Start when the captain announces final descent. This is 20 to 30 minutes before touchdown.
• If baby just ate: use a pacifier instead. Sucking is what matters.
• If baby refuses both: they may cry. Cabin pressure equalizes during a cry too. Not a disaster.

During the flight

• Most newborns sleep through flights. The white noise and rocking are soothing.
• If awake, talk, sing softly, walk the aisle, change positions.
• Diaper changes happen in the lavatory. Some have a tiny changing shelf (it varies by aircraft). For domestic flights, ask the flight attendant where to change.
• Skip blankets on a sleeping baby in your lap (overheating risk and AAP recommends against loose blankets).
• Use your carrier on board if you want to walk the aisle. The plane's seatbelt sign rules apply, but if it's off, walking is fine.

The on-board kindness moves

• If baby cries hard, walk to the back of the plane near the lavatory. The other passengers and crew won't mind.
• Skip the "sorry about baby" candy bags with earplugs for neighbors. They're cute but no one needs them. Most people are kind. Those who aren't won't be swayed by a granola bar.
• Tip the flight attendant if they help in any meaningful way (warming a bottle, holding baby while you bathroom). Cash, even $5, lands well.

After the flight

• Re-acclimate slowly. Don't rush to do all the trip activities the first day.
• Watch for ear infection signs in the first 2 days: extra fussiness, tugging at ear, fever, refusing to feed lying down.
• Re-hydrate baby. Air travel is dehydrating; offer extra feeds.
• Reset sleep slowly if you've changed time zones. Babies typically adjust faster than adults.

The "wish I'd packed" list for first-timers

• A small fan (battery-powered, clip-on).
• A long phone charger.
• A nursing cover or thin muslin (privacy + light block).
• Snacks for you (one-handed, non-messy).
• A foldable water bottle that fits in the seat pocket.
• Plastic ziplock bags for diaper disposal between trash runs.
• An extra hair tie (yours, not baby's).

What to skip

• A full nursery's worth of gear. Don't pack what you can easily buy at the destination (you can buy diapers anywhere).
• A diaper bag plus a carry-on plus a personal item. Consolidate. One backpack-style diaper bag plus carrier on you.
• Travel cribs unless your destination doesn't have one. Many hotels and rentals provide pack-and-plays.
