I flew in JetBlue's private 'apartment' for a 6-hour flight. The extra space made business-class travel even better.

• I was on JetBlue's inaugural flight from New York City to Edinburgh.
• I spent the six-hour trip in its business class "apartment," called the "Mint Studio."

It's not often you get your own apartment in the sky.

When I joined JetBlue for its inaugural flight to Scotland on May 22, I wasn't expecting to be in its "Mint Studio," a space my flight attendant described as an "apartment New Yorkers would kill for." But when I saw "1F" printed on my boarding pass, I knew I was in for a treat.

The front row of business class, the Mint Studio is JetBlue's most spacious option, with prices from around $4,000. Business Insider paid a press rate of $1,300, including a return flight in the airline's "Even More Space" economy section.

While the "apartment" makes for a comfortable transatlantic flight, it's not something I'd splurge on. Here's what it's like.
