I'll comment for a fellow Nutmegger...
We just got back in March from WDW, and we flew Song out of JFK (because I missed the good deal on BDL.. and JFK was cheaper.. no biggie overall..sorry for the mini rant)
Anyway, I thought the service on Song was excellent. Clean, bright, and spacious (as spacious as an airline can be). Friendly service, and great in-flight entertainment thanks to built in televisions. They have great sandwhiches, although they were $8 (but big enough to share as a snack). Serve beverages for free: coffee, tea, juice, soda, etc.
Really a great airline. Flying them again this Summer out of Newark, and hopefully getting to fly them again in October.
Hope this helps!
