Check Out A 'Filthy' And 'Disgusting' British Airways First-Class Seat

First-class airline tickets are expensive. Prices can easily reach $15,000 per flight, and that's not even for the really opulent first-class suites that have become more prevalent on the most prestigious carriers.

Those go for as much as $30,000.

Just for the sake of comparison, Mercedes-Benz is offering its CLA sedan — an entire car — for $29,995.

For that kind of money, passengers in first class expect a fine glass of champagne, in-flight entertainment, and an environment free from ... dried-on stains and thick layers of dust.

That's why a YouTube video posted by British journalist Owen Thomas last weekend was so shocking. (CNN originally reported Thomas' experience.)

In the 29-second video — which has garnered more than 1 million views — Thomas documented his "filthy" first-class experience onboard a British Airways jet from London to St. Lucia.

Thomas grows increasingly annoyed as he shows off the "cheap, motel-esque" dried stains and deep layers of dust that encrust his very expensive seat.

"This is British Airways first class and it is absolutely filthy," the enraged journalist says in the video. "You see the marks on here you can just scrape off with your finger."

"It’s when you open your seat, the real horror begins. This is first class. This is British Airways first class. It’s disgusting," Thomas added.
