I flew Delta One on a 9-hour overseas flight. Here's what surprised me about the business class seat.

"After spending a dreamy week in Europe in August, it was time to fly home to New York. I booked a flight from Brussels to Atlanta with a connecting flight to John F. Kennedy International Airport in New York, so I'd have a nine-hour flight plus another two-hour flight. Luckily, though, I wasn't dreading the overseas flight too much because I was flying Delta One."

"Delta One is the airline's business-class seat on long-haul flights, offering lie-flat seats and a host of other amenities. I've flown Delta One once before, from New York to San Francisco on my honeymoon, so I was thrilled to see what it was like to fly Delta One internationally. My Delta One ticket for the flight from Brussels to Atlanta cost $1,356."
