[CenterlineT]

A few years back we flew to Centennial with one fuel stop in a T210M. It took about 7 hours of flying and 30 minutes refueling and stretching etc..
She was fine as she normally reads the paper and dozes off. It was shorter flying back at 17k with onboard OX but it was the same. I have not flown the 337D on such a long XC so I am not sure. It is of course noisier than the 210 and it is a bit more cramped but it is a joy to fly it but I don't know how she will feel being a passenger.
I have flown commercial twice to KDEN since and I am not sure if I want to fly any of the two birds on such a long flight. Of course I am a bit grumpy waiting to board and going through the TSA maze at KDEN every time.
We have an eclipse chasing flight to Texas coming up in April and I will have to take one of the two birds (most likely the 337) and will report back.
