Pros: Food - Free dinners even for economy class. Entertainment - Every seat has a TV that offers multiple languages and tons of blockbuster movies from a variety of genres. They also offer many television shows in multiple languages and genres and video games. Roomy- The seats are as non-roomy as any airplane. However, the flight attendants don't give you any trouble when you want to just get up and walk around and talk to people. It gives the plane a roomy atmosphere. You can go to spacier sections of the plane to hang out.

The flight was great. The flight crew were all gorgeous women who were very helpful. The seat situation is not as awarsome but only because I’m a 6’8” giant!
