You can't use your write your own passes for Star carriers. You'd need to have your dad pick up and fill out a ticket request (10 days for Int'l), or you can pick them up at the NRSA check in desk (position 1-2) @ SFO, or any city ticket office (they are thin white strips that look similar to a w.y.o ticket).
Fill the slip out, drop it off at any of the three places mentioned above (or have your dad take it to operations with him), and it should be waiting for you to pay for it in (at the most) 10 days (four days for domestic).
I've found it particularly helpful to go to the city ticket offices about :15 before they close, and see if they can process the entire thing right there. 9/10 times, it works.
Never heard of the SouthWest Letter...maybe I'd better start looking into that! Not sure if you'd want to pay 10% of WN's walk-up fare, though (the basis for all airline-discounted tickets). I think WN is still offering a $25/leg deal though, for employees and their dependents.
One interesting thing, one of my friend's dad is a pilot for DL, and he was talking about how they don't have paper tickets, but rather a credit-card type thing which stores all of the information a paper ticket would need. All they have to do is present the travel card to the CSR, who swipes it through their reader. Really beats having to carry around ticket stock...it's never there when you need it the most! The card would make it so much simpler...
Come to think of it, didn't UA try this a few years ago? (maybe 5)? I know my mom has her UA travel card, with imprinted seniority date and name, and I know I signed a few papers a few years ago with my mom and dad so that we'd each get a DL-like card...hhhmmm....have to talk to Jimmy G. about that one...
