(CNN) -- Once you've battled through the queues, check-in, extortionate on board snacks and cramped seating, it's no wonder so many economy airline passengers complain about flying "cattle-class."
In fact, if the four-legged racing celebrities being flown around the world in luxury are any indication, next time you might want to ask for an upgrade to "horse-class."
Each year thousands of race horses, breeding stallions and beloved pet ponies are flown across the world in plush airborne stables costing up to $50,000.
"It is a major undertaking," Chris Burke, co-owner and operating manager at International Racehorse Transport, which flies 5,000 horses a year, told CNN.
"Each air stable can hold three horses. So if you were traveling from Australia to England, three to a stall is the equivalent of economy ($17,500), two to a stall is business class ($30,000), and one horse on its own is first class ($50,000).
There might not be champagne and in-flight films, but pampered ponies flying first class can expect round-the-clock specialists, 40 liters of water, two hay bales and none of the hassle of airplane transfers.
No expense spared
One thoroughbred who stretched out in style was Australian champion Black Caviar, who flew from Melbourne to London's Heathrow airport in June.
No expense was spared when the celebrity horse, who remains unbeaten in a staggering 23 consecutive races, jetted across the world to compete at Britain's prestigious Royal Ascot in front of Queen Elizabeth.
The super mare, who has won more than $7 million in prize money, wore a full-body compression suit -- to help blood flow and water retention --throughout the 30-hour journey.
She was accompanied by two stablehands and one vet in her first-class stable, measuring 3.5 meters by 2.5 meters.
"She had a lot of attention," owner Colin Madden said. "Even before the plane took off, there were about 30 people taking photos while she was boarding.
"In the air, handlers were checking her pulse and making sure she was eating and drinking properly every hour."
Once loaded into her stable on the ground, Black Caviar was lifted into the cargo plane by a scissor lift.
"She'd never been in a plane before, so you can imagine how terrified she was hearing the engine," added Madden. "She was agitated for the first half hour but then she calmed down.
"The flight took a lot out of her. It was at the end of a long racing campaign and she never quite bounced back -- when she arrived in the UK she was tired and lethargic."
Despite the toll of the journey, Black Caviar didn't disappoint at Ascot, retaining her unbeaten record in the Diamond Jubilee Stakes -- just.
Just like humans, airplane passengers of the four-legged variety must also contend with the risk of respiratory infections, dehydration and sleep deprivation.
Then there's the bureaucracy involved -- race horses also need passports and must pass quarantine before entering a new country.
International horse racing circuit
So why are an increasing number of owners and breeders flying their prized pets across the planet at such a massive cost -- and potential risk to their performance?
"It's very tempting from an international prize money point of view," Burke said.
"Hong Kong and Dubai in particular have been pioneers in trying to push an international horse racing circuit. To say 'we're attracting the best race horses from across the world' gets major publicity for their event."
The prestige associated with an internationally recognized race horse can also boost their breeding value after they leave the track.
"We thought we had a world class horse who deserved to perform on a world class stage -- it wasn't about prize money for us," Madden said of the decision to fly Black Caviar to Ascot.
"I think a lot of owners compete their horses internationally out of a mixture of pride, excitement and business acumen."
Sometimes though, no matter how much you prepare for a plane journey, there are some hiccups you can't avoid.
"One time in Sydney we were loading breeding studs aboard a Boeing 747 bound for Europe," Burke explained.
"It was going down the runway when all the rumbling must have set off the alarms on some of the Volkswagens which were also being transported."
Unsurprisingly, "the horses didn't like the idea of that," and the plane was promptly turned around and the car batteries cut off.
After all, as Burke explained: "The horses were worth a lot more than the cars on board."
