Just what is the average turn time now for Delta planes vs Song planes? I was under the impression that Delta planes are on the ground for about an hour. At least that's how long my plane has stayed on the ground when I didn't have to switch on a one-stop flight. How much shorter is Song's turn time? A recent announcement of their new Vegas and Ft Myers schedule doesn't impress me much regarding their "improved" turn around time:

JFK to Las Vegas 9:15 pm 11:45 pm
Las Vegas to JFK 12:35 am 8:15 am

Boston to Las Vegas 6:15 pm 9:03 pm
Las Vegas to Boston 9:55 pm 5:48 am

Boston to Ft. Myers 10:05 am 1:22 pm
Ft. Myers to Boston 2:15 pm 5:15 pm

The turn time is about 50 minutes each! What's the real deal here?
