code ti1 also rejected at phx recently. Normally I would just go through the kiosk but the kiosk did not let me finish registering and told me to go to counter. I also checked my confirmation email and it told me to go to counter. I booked a backup reservation and that one DID have a picture of a kiosk and told me to go to kiosk to avoid line instead of counter like what ti1 told me to do. the guy told me code was for master-tech or tech-masters

I might be going back to national with their corporate codes now.
