Mikhail Galin loves his cat Viktor, that’s for sure.

The 34-year-old Russian and his feline flew from Riga, the capital of Latvia, to Moscow without any incident on Nov. 6, but when Galin checked in for an 8.5-hour flight to his destination in Vladivostok, he was told Viktor was too fat to fly in the cabin.

Officials from Aeroflot — Russian Airlines — told Galin there was an 18-pound limit for companion animals checked into the cabin, and at 22 pounds, the chonktacular Viktor was just too much chonk to hang with his human in business class. Instead, Viktor would have to tough out the long flight in cargo.

But Viktor was already stressed from traveling, and Galin wouldn’t take the flight without the cat by his side.

“I was very worried that during the duration of an eight-hour flight, something would happen to him in the cargo and he wouldn’t survive the trip,” Galin told the Washington Post.

When he couldn’t persuade Aeroflot to let him board with Viktor, Galin turned to social media for help and found a couple sympathetic to his cause. Their cat, Phoebe, looked like a miniature Viktor.

Galin booked a business class ticket, met up with the couple at Sheremetyevo Airport in Moscow, and presented Phoebe as the cat he was taking with him on the flight. After airline employees weighed Phoebe and waved Galin forward, he and his new friends switched Viktor back in for his smaller body double and parted ways.

The plan worked beautifully and Galin would have gotten away with it if he hadn’t celebrated the successful swap on social media. He couldn’t resist the temptation and posted photos of Viktor on the flight: One shows the chubby cat peeking out of his carrier next to a glass of champagne, while another shot has Viktor in Galin’s lap, man helping cat enjoy a bird’s eye view.

The post went viral, an unamused Aeroflot got wind of it, and after an investigation the company docked Galin almost 400,000 frequent flier miles, his entire stash. It also booted him from its bonus miles program entirely.

“The law is harsh, but it is the law,” Galin told NBC News, repeating a stoic Russian maxim about punishment. “I violated the rules, and the carrier has every right to take action.”

Thankfully the result wasn’t all bad and Galin was rewarded for his loyalty to his cat. He told the Post several cat food companies had offered a year’s worth of food free for the flabby feline, and other transportation companies offered free use of their services.

While one politician called for Aeroflot to relax its rules on pet weight, the government wisely stayed out of kitty affairs.

“I don’t believe the Kremlin can or should comment on a situation involving a cat,” a spokesman for Vladimir Putin deadpanned.

As for Viktor, he’s made it clear he expects the same level of comfort next time he flies.

“He liked business class a lot better than economy class,” Galin said, “because he considered himself superior.”
