Airline ESA Letter Policy – United Airlines (2025 Guide)

United Airlines has followed suit with other carriers, discontinuing ESA-specific recognition. ESAs must meet pet travel policies.

ESA Travel on United Includes:

• Limited to cats and dogs
• Pet travel fee: $125 each way
• Must fit in a carrier under the seat
• No ESA documentation needed or accepted for flight privileges

International Flights:

Different rules may apply—some international United routes still allow ESA recognition depending on country laws.

Final Thoughts: United’s ESA policy requires planning ahead to treat your ESA as a pet. Your ESA letter remains important for housing, but not for travel. You can read United’s complete pet policy at:
