Tonight I flew on an AirTran 717, N985AT, and was surprised to see bright blue leather seats in coach. I was just wondering why they would make this change now, since the merger with Southwest is about to take place. Won't Southwest want to put their own interior in the AirTran planes so the fleet will be standardized? I was also on a 737 today which still had the cloth seats. I also noticed on both flights that the captain didn't call out Departure Check, Landing Check, and Arrival Check, as they did previously. Instead they used the double chime. Is this also part of standardizing procedures to match Southwest?
