I really like the way they sent first class to board first, and then, second they sent the rows 14 and up and last the middle section. It was less crowded and I've always wondered why that has never happened before it just makes sense that way. Board a lot quicker. Awesome plane ride. I loved it. Thank you so much.

Flight was overbooked x 4 and this caused a delay in boarding. The staff person that was in charge of boarding was professional and cool headed despite the stressful situation.
