Not necessarily true. The first flight (IAD-EWR) had an 8:15 a.m. departure. Extraordinarily unlikely that the crew was coming from another flight. The gate agents did not know where the crews were on any of these flights and at times lied about the causes of the delay (weather--it's always terrible somewhere) and they lied to other passengers about whether they could make their connections (telling most people yes when this could not possibly be the case). And the gate agent in EWR told passengers with connections that he didn't know anything about IAD so he couldn't tell them how to get from the A gates to the C gates. Would it have taken much time to learn a bit about this so passengers knew what they had to do? I was able to speak to several passngers and let them know what they had to do.

Whatever the causes of the delays, they are unacceptable if they occur almost all of the time.
