We just returned from WDW, flying Song from LAX to MCO. No problems to report whatsoever. Departure left on time and arrived about 5 minutes late. The flight attendants were cheery, but not obnoxious about it. They even cracked some jokes that made a few of us LOL.
I was hoping the in-flight entertainment system would have been setup by our trip since it was a cross-country jaunt, but I had to be satisfied with my book. I hear the entertainment systems are a slow rollout for their fleet. The menu choices for food were also decent, although the entrees should have been about $1 cheaper each, IMHO. I sucked it up and bought a turkey on focaccia sandwich for $8. It was a very good sandwich, but more along the lines of a $6-$7 product.
Overall, I was very satisfied with the experience and would fly them again if the fares are right.
