I don't know what to tell you about parking. I doubt that they'll let you park in our lot by the guard Shack, but there's a lot across the street for the big ups ops center that I don't think requires access. Would be a very short walk. Taxi from the terminal but you'll likely **** off that driver. Might consider parking at the holiday Inn (I think it's south) and for a tip their driver will take you to the guard Shack. Our jumpseat desk might have info on sdf parking for you. You can park at the training center but getting picked up may be an issue. Short walk to the employee's entrance but I don't know if they'll process jumpseaters there
Once inside ops they'll help you find your crew.
In Phoenix you'll go with the crew and sit in one of our luxurious gateway crew lounges. Bring food. The crew will be catered but you might not be.
