Sky Harbor to Tucson shuttle
 

Any experience with these? Is there one company you would recommend?

We have always used Arizona Shuttle. I am pretty sure they were the first shuttle service between Tucson and Sky Harbor.

Although I haven't used them between Phoenix and Tucson, I have used them between PHX and Flagstaff & Grand Canyon, I can recommend Arizona Shuttle too.

Thanks for the recs. I will look at Az Shuttle.

I have used Arizona shuttle many, many times from Phoenix to Prescott and back and they are wonderful. Clean, courteous and on time!

There used to be another competing shuttle service, but I think Az shuttle is only one in existence now.
It has about 3 stops in tucson, so you need to know which one will be most convenient.
