While continuing the thread w/o sidetracking it, I wanted to post a related question: Will I have enough time with a group of 9 college undergrads arriving into ORD at 5:07 AM from Sao Paulo to catch the "El" and transit to Union Station in time for a 8:14AM train to Champaign-Urbana? We will already have our train boarding passes in hand and I know the route quite well from ORD-the Amtrak boarding area. I think there is only another flight arriving from FRA and perhaps from DEL within the same hour to ORD. I have done this trip using the El and Amtrak before, but never so early in the morning. The last time immigrating through ORD was a snap, but I usually arrive in the late-morning or early evening. All students are US citizens with the exception of a Canadian.

If a 3-hour layover isn't enough, we would have to wait until 4:25PM, which is pretty unreasonable....

Thanks!
