Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Airport behavior varies; the published allowance still governs.
Delta Air Lines liquids policy
TSA 3-1-1: containers up to 3.4 oz (100 ml) in one clear, quart-size zip-top bag per passenger. Medical and infant-liquid exceptions have separate screening rules.
Family & Infants
Infant (under 2)
Under 2 on an adult's lap: free within the US; international fares are generally 10% of the adult fare plus taxes/fees. Add the infant to the reservation.
Stroller
Strollers can be checked free before security or at the gate, outside the ordinary bag allowance. Wagons and portable cribs count as checked baggage.
Car seat
Child-restraint seats can be checked free. Onboard use needs an approved restraint and a suitable seat, following manufacturer and aircraft seating restrictions; reserve a child seat to ensure availability.
Children's allowance
A child traveling free has no extra bag allowance. Discounted international infant tickets may include a checked bag, with transatlantic/Latin America Basic exceptions. Standard allowance applies at 50% or more of the adult fare; confirm the ticket.
