Delta Airlines is one of the largest carriers in the world and has a detailed pet policy that changed significantly following the U.S. Department of Transportation's 2021 rule change on emotional support animals. This guide covers Delta's current in-cabin pet policy, fees, carry-on requirements, and what ESA owners need to know in 2026.
Delta's 2026 In-Cabin Pet Policy
Delta allows small cats and dogs to travel in the cabin on most domestic U.S. flights. Key requirements:
- Fee: $95 per pet, per one-way flight (domestic US); $125 for international
- Container size: Soft-sided carrier must fit under the seat in front of you (max 18" × 11" × 11")
- Weight limit: Pet plus carrier must not exceed 20 lbs total
- Eligible animals: Cats and dogs only
- Age minimum: Pet must be at least 10 weeks old (domestic) or 16 weeks old (international)
- Per flight limit: Only one pet per passenger; maximum 4 pets per cabin
Delta does not allow pets in-cabin on international flights to/from the UK, select other international routes, or Basic Economy fares. Always verify with Delta directly before booking.
Delta ESA Policy 2026: What Changed
Delta no longer accepts emotional support animals as a special category of in-cabin animals. This change took effect in January 2021 following the U.S. Department of Transportation's rule update, which gave airlines discretion to treat ESAs as pets rather than service animals.
What this means for ESA owners traveling on Delta:
- ESA letters are no longer accepted to waive pet fees or bypass size limits on Delta flights
- If your ESA is a small dog or cat that fits within Delta's in-cabin pet requirements, you may travel with them as a standard pet (paying the $95–$125 fee)
- If your ESA is a larger dog that does not fit under-seat requirements, they must travel as a service dog (if trained to perform specific disability-related tasks meeting ADA standards) or as cargo
This change applies to flying only. Your ESA letter still provides full housing protections under the Fair Housing Act (42 U.S.C. § 3604) - an ESA letter remains one of the most important protections an ESA owner can have for housing rights.
Psychiatric Service Dogs on Delta
If your dog is trained to perform specific disability-mitigating psychiatric tasks - not just provide comfort or emotional support - they may qualify as a Psychiatric Service Dog (PSD) under ADA standards. PSDs are accepted on Delta flights at no additional charge. Delta requires advance documentation for PSDs, including the DOT Service Animal Air Transportation Form. See our full PSD letter guide for the distinction between ESAs and PSDs in air travel.
Delta Cargo Pet Policy
Delta accepts pets as checked baggage or cargo through Delta Cargo on select routes. The program was previously paused and has limited availability - check Delta's website directly for current route availability, breed restrictions (brachycephalic breeds are commonly excluded), and temperature restrictions.
ESA Letters Still Matter for Housing
While ESA letters no longer provide airline travel benefits on Delta, they remain critical for housing. Under the Fair Housing Act, your landlord must allow your ESA regardless of breed restrictions, weight limits, or no-pets policies - and must waive all pet fees. If you need an ESA letter for housing, The Supportive Pet can help with same-day telehealth evaluations. See our full guide to ESA letters for housing.

Frequently Asked Questions
Does Delta still accept ESA letters in 2026?
No. Delta stopped accepting ESA letters for special in-flight accommodations in January 2021 following the DOT rule change. ESAs are treated as regular pets on Delta and must meet standard in-cabin pet requirements (size, weight, fee) or travel as cargo.
Can I bring my ESA on Delta for free using my ESA letter?
No. Delta's current policy does not grant fee waivers for ESA letters. The $95–$125 in-cabin pet fee applies regardless of ESA status. Only trained psychiatric service dogs that perform specific disability-related tasks are exempt from fees.
What is the difference between an ESA and a psychiatric service dog on Delta?
An ESA provides emotional comfort through companionship but is not trained to perform specific tasks. A psychiatric service dog performs specific, individually trained tasks that mitigate a disability (e.g., interrupting a panic attack, alerting to dissociation). PSDs meet ADA service animal standards and travel fee-free on Delta. ESAs do not qualify for this status.
