We have safely arrived in Virginia. Our layover in Chicago was whittled down from a comfortable 2-hour lunch break to a 15-minute brisk walk, so we're hungry, but aside from that, the trip went smoothly. I did have a few concerns about the Embraer's landing gear making funny noises on the second leg, but it held up okay on the landing.
We didn't even get too much hassle at the luggage inspection point, although the fellow operating the X-ray machine for our suitcase did have to check with his supervisor about something.
