This was our first flight on an airbus with two levels, it carried about 525 passengers. The entire flight was fine, we did pay for exit row seats which gave us extra leg room. The attendants were pleasant and helpful. The food was fine going out as we had dinner and breakfast. The screen that we had to watch movies etc. on was very dark and sometimes difficult to see the image.Considering the amount of people getting on and off we believe they did a good job.
