Yes 1 hour fly time (DC to Knoxville)- it is always posted at 90 minutes but actual air time is 60-75 minutes usually. Driving is about 8 hours (500 miles) with only adults who don't need to stop much and can be much worse with holiday traffic. I-81 is pretty bad during holiday rush.
Anyway, agree w/ above posters, it is probably too risky to go the lap route. I have flown at least 10 times with him and have never been asked for proof of age; but probably not worth the risk.
