I did a trip from austin,tx to las vegas, nv two weeks ago (960 nm). Pretty sweet stuff, started talking to houston center and ended up with los angeles center when approaching klas. Just make sure to go with another pilot so you can nap on the way. Its not the optimal range of the cirrus nor the most comfortable ride for pax, but if you are doing it for the adventure then its quite a ride! Got to fly over west texas plains, deserts, mountains and also through different weather systems. Return flight sucked after being in vegas for three nights even though we saved a buffer day and night for rest before flying.
