Can you bring a diaper bag on a plane with Delta Air Lines when traveling with a baby?

 

Bringing a diaper bag on Delta Air Lines

 

Yes — Delta permits a diaper bag when you travel with an infant. For passengers traveling with a baby, a diaper bag and essential baby supplies are allowed in addition to your standard carry-on and personal item. Below is clear, practical guidance so you can travel calmly and prepared

• What you may bring: A diaper bag containing diapers, wipes, clothing changes, pacifiers, bottles, breast milk, formula, baby food, and necessary medications is allowed. These items are treated as infant necessities and are permitted even if they exceed the usual small-liquids limits.
• Security screening (TSA) tips: Declare breast milk, formula, and baby food at the security checkpoint. These liquids/gel items are exempt from the 3-1-1 rule and will be screened separately. Be prepared for screening staff to inspect or test contents; you may be asked to open containers or have them swabbed for testing. Ice packs are allowed; if frozen solid they usually pass as-is, but if partially thawed they may require extra screening.
• Carry-on allowance and stowage: Delta’s standard policy allows one carry-on bag and one personal item per passenger. When traveling with an infant, a diaper bag is accepted as a child-related item and often is allowed in addition to those standard items. Still, the diaper bag should fit under the seat in front of you or otherwise be stowed safely during taxi, takeoff, and landing. If the bag is too large, gate agents may ask that it be gate-checked.
• Strollers and car seats: Strollers and car seats are typically allowed free of charge and may be gate-checked at the aircraft door. If you purchase a seat for your child, you may use an FAA-approved car seat onboard — check that the car seat is approved for aircraft use and follow installation instructions. If your child will be on your lap, the car seat may be gate-checked or checked at the ticket counter.
• Packing and travel tips: Pack essentials (diapers, wipes, a change of clothes, feeding supplies) in the diaper bag so they’re easily reachable during the trip. Consider separate clear bags for used items and soiled clothes. Keep important items accessible for security checks. Label the diaper bag with your name and contact info in case it’s gate-checked.
• International and airline-specific details: While the general allowances above are routinely accepted, rules can vary slightly by country or flight. For international travel, allow extra time at security and check for any destination-specific rules for transporting breast milk or medication. If you’re unsure, ask Delta staff at check-in or the gate — they will confirm local procedures.
