Delta Air Lines medication liquid rules
Essential liquid medicines are exempt from the 100 ml rule on Delta Air Lines flights. You can carry more than 100 ml in hand luggage if you have supporting documentation — usually a prescription or a doctor's letter — and declare it at the security checkpoint.
Send these rules to whoever you're travelling with.
What to know before you pack
- Keep medicines in their original labelled packaging so the name matches your documentation.
- Insulin, inhalers, liquid painkillers, eye drops and gel cold packs used medically all count as essential medicines.
- Split your supply between hand luggage and hold luggage where possible in case of delays or lost bags.
- Baby formula, breast milk and juice for infants are exempt in reasonable quantities.
- Prescription medications are exempt with the container labelled and declared to TSA.
- Spare lithium batteries and vape devices must be in carry-on only.
