United Airlines charges $200-$700. Delta Air Lines limits pet cargo to qualifying active-duty military and State Department Foreign Service travelers with active transfer orders. Both airlines restrict snub-nosed breeds and require pets over 20 lbs to fly in cargo. United’s consumer page covers in-cabin travel. CitizenShipper’s ground transport averages $300-$400 for the same routes with door-to-door service and no breed restrictions. Let’s find out more about their pet cargo costs and policies, as well as any complimentary services they might offer!
Delta vs. United Pet Travel: Key Differences
| Feature | Delta | United |
|---|---|---|
| Cargo / unaccompanied pet availability | Highly limited. Delta has suspended general pet-in-hold/checked-baggage service and accepts pets as checked baggage only for qualifying active-duty U.S. military and State Department Foreign Service travelers with active transfer orders. | PetSafe available for eligible unaccompanied pet shipments through United Cargo. United Cargo continues to list PetSafe-servicing facilities. |
| In-cabin pets | Small dogs, cats and household birds may travel in the cabin on eligible routes. The pet must remain in an approved kennel under the seat, ensuring they have enough legroom during the flight. | Small dogs and cats may travel in the cabin on eligible flights, subject to United’s carrier, route and aircraft restrictions. |
| Domestic age minimum | 10 weeks for domestic travel. Pets entering the U.S. from another country must generally be at least 16 weeks old. | United’s pet policy sets minimum-age requirements based on the itinerary and applicable regulations; travelers should verify the current requirement for their specific route when booking to enjoy the best mileage perks. |
| Kennel / size limits | Pet must fit comfortably in the kennel and the kennel must fit under the seat. Delta recommends a soft-sided kennel up to 18 × 11 × 11 inches, although allowable dimensions vary by aircraft. | Cabin pets must fit in an approved carrier that can be stowed beneath the seat. Cargo kennel requirements vary according to the pet, aircraft and shipment. |
| Breed restrictions | Delta does not accept brachycephalic dogs or cats as checked baggage. Cabin restrictions can also apply by route and aircraft. | Breed restrictions can apply to PetSafe/cargo shipments, including restrictions associated with brachycephalic breeds, kennel size, aircraft and temperature. |
| Fees / pricing | Cabin pets travel for a one-way pet fee, with the amount depending on the itinerary. Qualifying military/Foreign Service checked-pet travel is subject to applicable fees. | Cabin pet fees apply on eligible itineraries. PetSafe shipments require shipment-specific pricing through United Cargo rather than a standard consumer pet fee. |
| Booking | Cabin pets should be arranged with Delta in advance because the number of pets allowed per flight is limited. Qualifying checked pets must be booked at least 48 hours before departure. | Cabin pets are added to eligible reservations, while PetSafe shipments are arranged through United Cargo. |
| Military / Foreign Service exception | Yes. Qualifying active-duty U.S. military and State Department Foreign Service personnel, plus eligible spouses/dependents, may use Delta’s checked-pet exception when traveling with qualifying transfer orders. | No comparable military-only restriction for PetSafe. United’s cargo pet service is available based on its eligibility requirements rather than being limited to military or Foreign Service travelers. |

The Pet Transport Process: An Overview
Before diving into the comparison, let’s briefly discuss the general pet transport process. This will help you understand what to expect when transporting your pet via air travel.
- Pre-travel preparations: Obtaining necessary documentation, ensuring your pet is healthy, and preparing them for the journey.
- Booking the flight: Depending on the airline and your pet’s size, you may need to book a separate reservation for your pet.
- Check-in and boarding: On the day of the flight, you must check your pet in, provide any required documentation, and make sure they are safely and securely boarded.
- In-flight care: During the flight, airline staff will monitor and care for your pet to make sure they remain safe and comfortable.
- Arrival and pick-up: Upon arrival at your destination, you must collect your pet and complete any necessary paperwork or procedures.
Now that we have a basic understanding of the pet transport process, let’s compare Delta Airlines and United Airlines.
Consider Ground Transportation as an Alternative to Air Travel
With many restrictions around pet air travel, ground transportation is often a better solution. It’s a safe, very reliable, and very humane way to send a pet long distances.
Delta Air Lines Pet Transport: Key Features
Delta Airlines does not offer pet transport, even if you’re in first class on Delta One, through its Delta Cargo service because that service was discontinued. That service is even discontinued if you fly across the globe. Pet transport is limited to military personnel only. However, you can still take a dog inside the cabin if it’s small enough to fit in a carrier under your feet in front of you.
United Airlines Pet Transport: Key Features
United Airlines provides pet transport through its PetSafe program. Here’s what you need to know about United’s pet transport service:
United’s PetSafe program offers climate-controlled environments for pets during travel, with personal handling and monitoring throughout the journey. Their dedicated PetSafe team is available 24/7 for assistance. Like Delta, United Airlines has size and breed restrictions for pet travel. Small pets can travel in the cabin, while larger pets are shipped as cargo. United also restricts certain breeds from travel due to health concerns. Pet transport fees with United Airlines vary based on the pet’s size, weight, and destination. Prices generally range from $200 to $700 per pet.
Comparing Pet Transport Options: Delta Airlines vs. United Airlines
When comparing pet transport options between Delta and United, consider the following factors:
- Both airlines provide climate-controlled environments for pets and offer 24/7 customer support.
- Size and breed restrictions are similar for both airlines.
Both Delta and United allow small pets in the cabin, but only United allows larger pets shipped as cargo. Specific breed restrictions apply for both airlines.
- Pet transport pricing varies for Delta and United Airlines, depending on factors such as the pet’s size, weight, and destination. However, the costs are generally comparable, ranging from $200 to $700 per pet.
Delta and United Additional Services
Both Delta and United Airlines offer additional services to make pet transport as smooth and stress-free as possible. These services include:
- Assistance with pre-travel preparations, such as obtaining required documentation and ensuring your pet meets health requirements.
- Access to a network of pet travel professionals who can help you navigate the complexities of international pet transport regulations.
- Tracking capabilities to monitor your pet’s progress during the journey.
Airline-Approved Pet Carrier Requirements
Choosing the right travel carrier is crucial for your pet’s safety and is a strict requirement for both Delta and United. Both airlines adhere to IATA (International Air Transport Association) regulations for pets traveling in cargo. So let’s explore what this means for you!
- The carrier must be made of rigid material like hard plastic, wood, or metal, with a secure, spring-loaded lock on the door. The hardware must be metal nuts and bolts—plastic latches are typically not permitted for cargo travel.
- Proper ventilation on at least three sides is mandatory.
- The crate must be large enough for your pet to stand up, turn around completely, and lie down in a natural position.
- For in-cabin travel, soft-sided carriers are often allowed, but their dimensions must fit under the seat in front of you.
Always measure your pet and compare it to the specific dimension limits listed on each airline’s website before purchasing a carrier, as these rules are strictly enforced at check-in. Remember to label the carrier clearly with ‘Live Animal’ stickers and your contact information.
Health Certificate and Vaccination Rules
Both Delta and United require a valid health certificate, often called a Certificate of Veterinary Inspection (CVI), for pets traveling in cargo. This document must be issued by a licensed veterinarian. For most domestic travel within the United States, the certificate must be dated within 10 days of your flight. It needs to confirm your pet is healthy enough for air travel and is free of infectious diseases.
The certificate must include your pet’s breed, age, and up-to-date vaccination records, especially for rabies. Most airlines mandate that the rabies vaccine was administered at least 28-30 days prior to the travel date.
For international flights, the requirements are far more complex and may require specific USDA APHIS endorsements and additional forms depending on the destination country. Always confirm the exact CVI timeline and destination-specific health requirements with both the airline and the destination country’s consulate well in advance of your booking.
Restricted Breeds: Brachycephalic Dogs and Cats
A major consideration when choosing between Delta and United is their policies on specific animal breeds. Both airlines have strict restrictions on transporting brachycephalic, or ‘snub-nosed,’ dogs and cats due to their increased risk of respiratory issues at high altitudes and in fluctuating temperatures. These breeds are often prohibited from traveling in the cargo hold. Let’s take a look at which breeds are affected.
- Commonly restricted dog breeds include all types of Bulldogs (French, English, American), Pugs, Boxers, and Boston Terriers.
- Restricted cat breeds often include Persians, Himalayans, and Burmese.
- The full list is extensive and can include mixed-breed animals that exhibit brachycephalic features.
- While some of these breeds may occasionally be permitted to fly in the cabin if they meet size and weight requirements, their travel in cargo is almost always banned.
- Because these lists are updated to make sure animal safety, you must check the most current breed restriction page on the official Delta and United websites before planning your travel.
How to Save Money on Pet Air Cargo
Regardless of whether you choose Delta Airlines or United Airlines for your pet’s travel needs, taking the necessary steps to Make sure a successful experience is essential. Here are some tips to keep in mind:
- Research airline policies: Familiarize yourself with the specific pet transport policies of the airline you choose. This will help you understand their requirements and restrictions.
- Schedule a pre-travel veterinary check-up: Make sure your pet is healthy and up-to-date on vaccinations before the trip. Obtain any necessary documentation, such as health certificates or vaccination records.
- Select an appropriate pet carrier: Invest in a high-quality, airline-approved pet carrier that provides ample space and ventilation for your pet.
- Prepare your pet for the journey: Help them acclimate to the travel carrier by allowing them to spend time in it before the trip. Make sure your pet is comfortable and familiar with the carrier to reduce stress during the journey.
- Label the carrier: Clearly label your pet’s carrier with your contact information and any special instructions for airline staff.
- Pack essential items: Provide a comfortable blanket, a favorite toy, and any necessary medications for your pet during the trip.
- Stay informed: Keep track of your pet’s progress during the journey using the tracking capabilities provided by the airline.
CDC Rules for Dogs Entering the United States
The CDC has specific requirements for dogs entering the United States. Under the current rules, dogs must appear healthy, be at least 6 months old, have a microchip, and have a CDC Dog Import Form receipt. Additional documentation may be required depending on where the dog has been in the past six months and its rabies vaccination history.
These requirements apply to dogs entering the United States, including dogs traveling by air. They do not mean that airlines broadly prohibit all dogs from high-risk rabies countries. Instead, travelers may face additional CDC documentation and entry requirements based on the dog’s travel and vaccination history, as well as separate airline policies.

Why Ground Transport Costs Less Than Air Cargo
Ground pet transport usually costs less than air cargo because it avoids many of the extra fees and logistical costs associated with airline travel. When shipping a pet by plane, owners often pay for airline cargo handling, airport processing, specialized airline-approved carriers, and sometimes even a ticket for an accompanying passenger or air nanny. These costs can quickly add up, especially for large pets that must travel in the cargo hold.
Ground transportation, on the other hand, typically involves fewer overhead costs and more flexible routing. Professional drivers, such as those you can find on marketplaces like CitizenShipper, can transport multiple pets along similar routes, which helps reduce the per-shipment price. Because ground transport also eliminates airport fees and airline restrictions, it often becomes the most affordable option for long-distance pet travel while still providing safe, climate-controlled transport.
