Update on topic: I did the 24 hr check in and was happy to see that we got A46 and A47. Not having flown when I didn't have an assigned seat, I was wondering how this would work. We lined up in the A 31- 60 line and when we got on the plane, all the window seats and aisle seats were taken, leaving row after row of middle seats. Since you generally want to sit with your traveling companion, this wasn't so good. we did manage to find a middle seat and aisle seat near the back of the plane. On the return flight, I was at the computer at exactly 24 hrs before the flight and this time we got B 15, 16 tickets. The return went a little smoother and my husband did get a window seat and I got the middle. Once we figured it out, it wasn't so bad and I would fly sw again and I don't think I would spring for the extra 50.00 for the early bird seating. I did hear a lot of people complaining about the seating arrangement. Plane was full, coming and going!
