I've always wondered why the Shuttles don't operate slightly later flights. From DCA-LGA, DL's last flight is at 8:30 PM and US at 9PM. Is there any reason they don't operate to 10 or 11PM?
Seeing that NYC is a 24 hour city, and DC isn't bad itself, I would think that later flights would be natural. Also, wouldn't businessmen like the option of staying late at work and catching a late flight?
Any thoughts are appreciated.
