How Live Animal Cargo Works: A Step-by-Step Guide for Pet Owners

Sending a pet in airline cargo for the first time raises a natural set of questions. What happens after you hand them over? Where do they wait? Is the hold pressurised? Who monitors them? This guide walks through the process from the moment you arrive at the cargo terminal to when your pet is collected at the destination.

Cargo Terminal vs Passenger Terminal

Unlike cabin pets, animals travelling as cargo are not checked in at the passenger terminal. You take your pet to the cargo terminal – a separate building, usually airside or at a dedicated freight facility. The cargo terminal for live animals is sometimes called the animal reception centre or live animal handling facility.

At major airports (Heathrow, Frankfurt, Amsterdam Schiphol, Dubai, Singapore Changi), these facilities have dedicated staff trained in live animal handling, temperature-controlled holding rooms and veterinary support.

Check-In Timeline

For live animal cargo, the cut-off time before departure is typically 3 to 4 hours, not the 2 hours commonly assumed. Some airlines require 4 to 5 hours for live animals on long-haul international flights. Confirm the cut-off time with your airline or agent well in advance – missing this window means your pet misses the flight.

At check-in, staff will:

1. Weigh the crate and animal together
2. Check the crate meets IATA specifications (ventilation, door latches, size)
3. Review all documentation (health certificate, microchip, import permits)
4. Attach the airline’s live animal tags and live animal stickers to the crate
5. Confirm the routing if there is a connection

In the Hold

The cargo hold of a modern wide-body aircraft (Boeing 767, 787, 777; Airbus A330, A350, A380) is:

• Pressurised to the same pressure as the cabin (equivalent to about 6,000 to 8,000 feet altitude)
• Temperature-controlled – most airlines maintain the live animal compartment between 15 and 25 degrees Celsius
• Not pitch black – some ambient light is present; it is not total darkness

Pets are typically placed in a designated section of the hold, sometimes separated from regular cargo by dividers. On wide-body aircraft, this is often in the forward lower hold where conditions are more stable.

Narrow-body aircraft (Boeing 737, Airbus A320) have smaller, less temperature-stable holds and are not ideal for live animal transport on long-haul routes. Most long-haul live animal cargo is routed on wide-body aircraft.

During a Connection

If your pet’s route includes a connection, they are offloaded at the hub airport, transferred to the connecting aircraft’s live animal facility, and loaded onto the next flight. Larger hubs (Frankfurt, Amsterdam, Dubai, Singapore) have dedicated live animal transfer facilities. At well-run facilities, connection times under 2 hours are manageable. Longer connections may involve a rest period in a holding area.

Transit countries sometimes impose their own inspection or documentation requirements. Ensure your routing is cleared for live animal transit at any stopover point.

Arrival at the Destination

At the destination, your pet is:

1. Offloaded from the hold
2. Taken to the destination airport’s live animal facility or cargo terminal
3. Inspected by customs veterinary officers (who check documentation and microchip)
4. Released to the owner or their authorised agent once clearance is confirmed

At airports with efficient live animal processing (Amsterdam, Singapore, Frankfurt), collection can happen within 1 to 2 hours of the flight arriving. At smaller airports with less infrastructure, this can take longer.

What to Do on Arrival

Go to the cargo terminal (not the arrivals hall) with:

• Your ID or passport
• The air waybill number (provided by the agent or airline)
• Copies of your pet’s documentation
• Leash or carrier for after release

Do not panic if it takes longer than expected. Veterinary inspection queues at busy hubs during peak seasons can take time.

Monitoring During the Flight

Airlines do not provide live video monitoring of the cargo hold during flight. The cabin crew cannot check on cargo animals mid-flight. Pilots are notified that live animals are on board and will monitor hold temperature readings from the cockpit, but direct observation is not possible until landing.

This is one reason why crate training and a pre-flight exercise session matter: a calm, well-rested dog in a familiar crate handles the wait better than an anxious animal in an unfamiliar box.
