Yeah, AS was ahead of most other majors when they rolled out the ITMs. Even in a station the size of PSP, they have five at the ticketing area and two out by their boarding gates. Pretty progressive, and I love using them whenever I fly AS. The MileagePlan bonus ends soon, however. So now I will start checking in on-line to get the 1K mile bonus, which should be in effect for a while longer, as it is the latest c/i initiative announced by AS.
Have also used CO's E-Ticket machines, which are about as simple as AS's. Hope DL's are widely accepted at whichever stations they elect to make them available.
