Delta Air Lines 100ml liquid rule
Delta Air Lines does not set its own liquid limit — the airport you depart from does. At most airports that means containers of 100 ml or less in one clear resealable bag. At airports with next-generation CT scanners you may be allowed up to 2 litres per container and can leave liquids inside your bag. Because Delta Air Lines flies from both kinds of airport, always pack to the 100 ml rule unless your departure airport is confirmed CT-equipped.
What to know before you pack
- Liquids go in one transparent resealable bag, roughly 20 × 20 cm, one bag per passenger, taken out at the X-ray unless the airport has CT scanners.
- The limit is the printed container size, not how much liquid is left inside it — a half-empty 200 ml bottle is still refused.
- TSA's 3-1-1 rule applies at all US airports: 3.4 oz per container, one quart-size clear bag, one per passenger.
- TSA is testing CT scanners at select airports where liquids may stay in bags, but 3-1-1 is still the default rule.

Frequently asked
Can I take 100ml liquids on Delta Air Lines?
Yes. Containers of 100 ml or less inside one clear resealable bag are accepted on every Delta Air Lines flight. Larger containers are only allowed where the departure airport has CT scanners and has publicly lifted the limit.
Does Delta Air Lines count the liquid bag as part of my cabin allowance?
The clear liquid bag travels inside your cabin bag, so it counts toward your Delta Air Lines hand luggage allowance (45 × 35 × 20 cm and up).
What happens if my liquid is over 100ml at Delta Air Lines security?
Security, not the airline, makes the call. Over-size containers are surrendered at the checkpoint — there is no fee, but the item is not returned.
