haha...don't count on that. Those "priority" bag tag are largely decorative at US airports, including DFW. They certainly do not dependably come out first.

2 hours should be fine for the connection, but I wouldn't anticipate much time in the lounge, you might have to choose between shower or dinner. Your ICN flight will land at Terminal D, I believe Alaska uses terminal E, so you'll need to Skytrain between the lounges in D and the departure gate.
