I spent 10 hours in Air France's most exclusive first class. My flight was so good I felt like I was on a private plane.

My Air France La Première flight from Paris to Houston cost nearly $15,000 for a one-way ticket. Amber Gibson I flew from Paris to Texas in Air France's exclusive La Première first class. The in-air food created by Michelin-starred chefs, spacious suite, and great WiFi impressed me. This is the most luxurious transatlantic flight I've ever been on, and I'm glad I tried it once. Air France's La Première first class is widely considered one of the most exclusive commercial airline experiences in the world, with only four suites per aircraft in a 1-2-1 configuration. The airline flies La Première to just a handful of US cities, including New York, Washington, Los Angeles, San Francisco, Miami, Atlanta, and Houston. So when I recently found myself traveling from Paris to Houston, I decided to give Air France's La Première class a try on my 10½ -hour flight.
