I need to get to a seminar at Columbia University in New York that starts at 4:45 on a Thursday. Which shuttle do I need to catch from DCA to get there on time?


Also, when do they close the doors on the Usair and Delta shuttles?

I will be cutting it close, because I can't leave DC until 1:20. If I got to DCA at 1:45 with my boarding pass printed out, could I make a 2:00 shuttle?


It appears that the shuttles are scheduled to take 1 hour and 20 minutes. So a 3:00 shuttle would get me there 4:20, which is almost enough time.

According to Google, it takes 19 minutes (up to 30) in traffic get from LGA to Columbia. Any tips for catching a cab quickly at LGA?
