There are dire predictions of tourist traffic gridlock but who knows.

Last time we flew to Wichita (outside the path of totality but closest available ticket we could get) to drive to Kansas City, to a spot with long duration not far from where I grew up. All in order to "see" the total eclipse I had been waiting for since I learned it was coming as a little kid. Was a great choice till it went full clouds with five minutes to go. Then we were in an absolute hoard of traffic getting back around Kansas City to head back to the return plane in Wichita. Then it started raining. Hard.

This time the estimate at the house in Fort Worth it is a bit under two minutes of totality. We could drive somewhere some distance away for double that. With a zillion other people. Think we're just going to wander out in the back yard this time.

If you check the duration map I think, but don't warrant, it is something a bit over two minutes total eclipse right over the airport just before noon. Just for doing nothing but getting outside where you can see. (Like walking to the top of a parking garage--or just out the door to the top of the low-rise parking at Terminal B). Max anywhere in Texas is maybe double that for what is likely to be a traffic-congested effort. (The in-between alternatives are taking the Tex-Rail towards Fort Worth out of Terminal B, but getting off at the forsaken middle of nowhere first stop commuter lot north of the airport (with no facilities but wide-open spaces). Or the second stop in Grapevine (a bit of standard old-downtown tourist spot that would be an interesting layover spot, but bound to be crowded and the view more obstructed).

Might get boring waiting for a flight after it is over. But other than that I would suggest saving the car rental money and staying at the airport. The eclipse is coming to the airport. You don't have to go to it.
