7 Critical Rules: Can Your Dog Fly Delta Airlines First Class In 2025?
Planning to upgrade your furry companion’s travel experience to First Class on Delta Airlines? As of December 22, 2025, the dream of a luxurious flight for your dog is possible, but it comes with a set of extremely strict and often surprising rules. Unlike the Main Cabin, First Class and Delta One cabins have unique restrictions—especially concerning space and international routes—that can lead to an immediate denial at the gate if you aren't prepared. This comprehensive guide breaks down the essential 2025 Delta Airlines pet policy, focusing specifically on the nuances of premium cabin travel.
The core policy remains: only small dogs, cats, and household birds (domestic flights only) that fit comfortably in a carrier under the seat are allowed. However, the tighter, more complex seating arrangements in First Class require meticulous planning, early booking, and a deep understanding of Delta’s critical limitations on the number of pets and specific international routes.
The Essential 2025 Delta Airlines First Class Pet Travel Checklist
Traveling with a pet in any premium cabin, including First Class, requires navigating a specific set of logistical and financial hurdles. The pet must be at least 10 weeks old for domestic travel and 16 weeks old for international travel, and must be completely contained within a kennel for the entire flight. Here are the most critical rules you must follow when booking First Class tickets for you and your dog.
1. The Strict "Two-Pet Per Cabin" Limit and First-Come, First-Served Booking
Delta Airlines enforces a hard limit on the number of pets allowed in each cabin class on every flight. This is the single most important factor for First Class pet travel.
- First Class Limit: A maximum of only two pets in a carrier are permitted in the Domestic or International First Class cabin per flight.
- Booking Priority: Pet slots are confirmed on a strict first-come, first-served basis.
Actionable Tip: You must call Delta Reservations immediately after booking your First Class ticket to secure your dog’s spot. Do not wait until check-in. If the two slots are already filled, your dog will be denied travel in that cabin, forcing you to move to the Main Cabin (if space is available) or rebook your flight.
2. The Absolute Ban on Pets in International First Class and Delta One
This is a rule that often catches travelers by surprise and is a non-negotiable policy for 2025.
- International Prohibition: Pets in Cabin (PETC) are not allowed in the Delta One, Business Class, or First Class cabins on any international flight, regardless of the aircraft type.
- Domestic Only: Flying a dog in First Class is generally restricted to domestic U.S. flights.
- Recent Embargo: Note that Delta has implemented an embargo for Pets in Cabin on flights originating in specific locations, such as the Dominican Republic, effective January 24, 2025. Always check Delta's official Pet Travel Overview page for the latest embargo list before booking.
If you are traveling internationally and wish to fly in a premium cabin, you must either book a Main Cabin seat or travel without your pet.
3. The Carrier Size Challenge: First Class Under-Seat Space is Smaller
While the overall policy for in-cabin pets requires the carrier to fit under the seat in front of you, First Class seats often have significantly less under-seat space than those in the Main Cabin due to the mechanics and structure of the larger, more advanced seats.
- Recommended Carrier Size: Delta generally recommends a soft-sided carrier, which is crucial for First Class. A common recommended dimension is around 18 x 11 x 11 inches (Length x Width x Height). Another source suggests a max of 18 x 14 x 8 inches.
- The First Class Caveat: The actual space varies dramatically by aircraft (e.g., Boeing 737, Airbus A321, etc.). The First Class seat often has a narrower or shorter space because of the footwell, seat controls, and entertainment boxes.
Pro-Tip: Always check the specific aircraft type and seat map for your flight. A soft-sided carrier is highly recommended as it can be slightly compressed to fit the tight dimensions, ensuring your pet’s comfort and compliance with the rules.
4. Understanding the In-Cabin Pet Fee Structure for Premium Travel
The fee for bringing your pet in the cabin is charged per segment, regardless of whether you are in First Class or Main Cabin. This fee must be paid at the airport check-in counter.
- Domestic Fee (U.S.): The one-way fee for a pet in the cabin is typically $125 to $150 USD per flight segment.
- International/U.S. Virgin Islands/Puerto Rico Fee: The fee is generally $200 USD per flight segment.
Note that this fee is separate from your First Class ticket price. You are essentially paying for the privilege of your dog occupying a valuable under-seat space.
5. Service Animals vs. Pets: A Crucial Distinction in First Class
The rules above apply only to standard "Pets in Cabin" (PETC). Trained Service Animals (SVAN) are governed by different regulations and are accepted in all cabins, including First Class, with necessary documentation.
- Required Documentation: For all service animals, the U.S. Department of Transportation (DOT) Service Animal Air Travel form is required.
- Long-Haul Flights: For flights of 8 hours or more, an additional Relief Attestation form must also be submitted.
Unlike pets, Service Animals are not subject to the two-pet-per-cabin limit and are not required to remain in a carrier if they can be safely accommodated at the passenger's feet without impeding the aisle or another passenger's space.
6. Health and Documentation Requirements for Your Dog
Regardless of the cabin class, your dog must meet basic health and documentation requirements. This is particularly important for international travel (where pets are banned from First Class, but you may be in a premium economy cabin).
- Age Requirement: Pets must be at least 10 weeks old for domestic travel and 16 weeks old for international travel.
- Health Certificates: While not always required for domestic travel, a health certificate issued by a veterinarian is mandatory for most international destinations and is highly recommended for all flights.
- Behavior: Your dog must be well-behaved and remain in the carrier at all times while in the airport and on the aircraft.
7. The Final Boarding Process and Gate Agent Authority
Even with a confirmed booking, the final authority rests with the gate agent and flight crew. They will perform a final check of the pet carrier size and your dog's ability to fit comfortably. If the carrier cannot be stowed properly under the seat in your First Class cabin, or if your dog appears distressed or too large for the carrier, you may be denied boarding or required to move to a different cabin or flight. This stringent enforcement ensures the safety and comfort of all passengers and crew.
Key Takeaways for First Class Dog Travel on Delta
Flying with your dog in Delta’s First Class is a premium experience that demands premium preparation. The primary hurdles are the severely limited number of spots (only two per flight) and the outright ban on pets in First Class/Delta One on international routes. By booking early, confirming your aircraft's specific under-seat dimensions, and using a compliant soft-sided carrier, you can ensure a smooth, luxurious journey for both you and your canine companion.
