TSA & Airline Rules for Flying with Breast Milk [2025 Guide]

Traveling with breast milk requires careful planning and knowledge of specific airline policies. As of 2025, while TSA and international security regulations generally allow breast milk through security checkpoints, individual airline policies can vary significantly. This comprehensive guide covers everything you need to know about flying with breast milk, from storage requirements to airline-specific rules.

TSA and International Security Regulations

The TSA classifies breast milk as a medical liquid, exempt from the standard 3-1-1 liquids rule. As of 2025, you can bring breast milk in quantities greater than 3.4 ounces (100ml) in your carry-on bag. However, you must declare these items at security checkpoints and present them separately for screening. Ice packs, freezer packs, and gel packs are allowed, even if partially frozen.

Major U.S. Airline Policies

• American Airlines: Allows breast milk in carry-on bags with no quantity limits. Offers cooling assistance on select international routes and access to power outlets for breast pumps on most aircraft.
• Delta Air Lines: Permits breast milk, formula, and cooling elements. Their 2025 policy specifically allows breast pump equipment as an additional carry-on item at no charge.
• United Airlines: Accepts breast milk containers up to 5.5 pounds in dry ice. Provides dedicated storage areas in United Polaris lounges for breast milk refrigeration.
• Southwest Airlines: No quantity restrictions for breast milk. Allows ice packs and provides complimentary ice on request for milk storage.

International Carrier Policies

International airlines typically have more varied policies. Emirates, for example, provides dedicated breast milk storage in their A380 first-class galleys. British Airways allows breast milk in both carry-on and checked baggage, with cooling assistance available on long-haul flights. Air France-KLM offers refrigeration services on select aircraft but requires 48-hour advance notice.

Storage Solutions and Equipment

Modern travel-specific milk storage solutions include the Medela Freestyle Flex ($399) and Elvie Pump ($499), both TSA-approved and designed for in-flight use. For cooling, the Packit Freezable Bag ($24.99) and Milk Stork cooling totes ($89-149) are airline-approved options that maintain proper temperature for up to 24 hours.

Step-by-Step Travel Preparation

• Contact your airline 48-72 hours before travel to confirm current policies
• Pack milk in clear, sealed containers (3-5 oz portions recommended)
• Bring printouts of airline and TSA breast milk policies
• Arrive at least 30 minutes earlier than usual for security screening
• Request ice from flight attendants immediately upon boarding

Common Challenges and Solutions

Long-haul flights present unique challenges. Qatar Airways and Singapore Airlines offer dedicated refrigeration services but require booking at least 72 hours in advance. For flights over 12 hours, consider the Ceres Chill ($69.99) or Yeti Daytrip Lunch Bag ($80) for extended cooling capacity. Some airport lounges, including American Express Centurion and United Club locations, now offer dedicated pumping rooms and refrigeration services.
