Infants (under 2 years, no seat): No carry-on allowance, but one diaper bag, breast pump with cooler bag, or soft-sided bassinet is permitted free, plus one collapsible stroller or car seat (gate-checked or carried onboard if space allows).
Children (2–11 years): Same allowance as adults.

Duty-free liquids in sealed tamper-evident bags (STEBs) are allowed with proof of purchase. Beverages purchased post-security are exempt from liquid restrictions.

Delta Connection Flights (50 seats or less): Only one personal item is permitted onboard due to limited overhead space; carry-on bags are gate-checked free with a pink Gate Claim/Planeside tag and returned upon deplaning.
Oversized carry-on bags may be gate-checked with fees ($85–$95, depending on itinerary, if exceeding checked baggage allowance).
Prohibited items include aerosols (e.g., cooking spray), sharp objects (e.g., knives, scissors), and self-balancing devices (e.g., hoverboards). Smart bags require removable lithium batteries carried separately.
Small musical instruments (within 22 x 14 x 9 inches) can replace carry-on; larger ones may require a purchased seat or be checked.
Additional permitted items: Umbrellas, coats, books, food, pillows, child seats, or bassinets (if space allows).
Flight attendants cannot assist with placing carry-on bags in overhead bins, except for passengers with disabilities.

Allowance: Items like golf bags, skis, and bicycles count toward the free baggage allowance if within weight (50–70 lbs, depending on class) and size (62 linear inches) limits.
Non-Accepted Items: Bags over 100 lbs (45 kg) or 80 linear inches (203 cm), Christmas trees to Hawaii (must pass agricultural inspection), and certain hazardous items (e.g., hoverboards).

Prepay baggage fees online (24 hours before departure) or use 3,000 SkyMiles for the first bag (domestic).
Measure bags (carry-on: 22 x 14 x 9 inches; checked: 62 linear inches) and weigh them (50–70 lbs) at home using a digital luggage scale.
Use lightweight luggage and roll clothes to save space. Wear heavy items (e.g., jackets, boots) to reduce bag weight.
Leverage Delta SkyMiles American Express Cards or Medallion/SkyTeam Elite status for free checked bags.
For codeshares (e.g., Air France, KLM), confirm the MSC’s rules, as they may differ.
Label bags with contact details inside and out.
Arrive early: 2 hours for domestic flights, 3 hours for international, to meet the 45-minute domestic baggage drop-off deadline. Online check-in (24 hours to 1 hour before departure) via delta.com or Fly Delta app saves time.
