I'm making a weekend out of it: JFK-BNA on Friday evening, coming back Monday night BNA-DTW-LGA after the eclipse.
Fortunately, I have a friend with a guest room in Nashville, so that's all taken care of. I booked the flight months and months ago with a 31 minute layover in DTW, hoping a schedule change would decrease that so I could go back direct. Looking like that's not going to be possible
