Easy boarding process and on time flight is what I liked Quality of food was poor Sat on middle row seat 35 where there is better leg room. However, crew and passengers walked all over the three of us who sat on that row to use it as a short cut to use the restrooms. Even letting the crew members didn't help. We could not relax during the flight.
