2 Hours at Sea Tac, enough time?
To get some good chow? Will be landing with Delta and flying out with Horizon. I am sure gate changes, etc will need to taken into consideration. I don't need sit down restaurant but can pick up and go.
I'd say no. Given that they say to be there 2 hours early and it takes at least 35 minutes to get to somewhere good in Seattle, you'd be pushing it for sure. There are some pretty good options in the food court area of the newish terminal to hit. Never really hit them myself, so you might search the board for other people's recs.
It's tough to get out of the gate and into good eating territory and back in under, say, an hour at SeaTac. Getting through security can be a nightmare. Agreed with BallardFoodie, I wouldn't risk leaving the airport.
Stay at the airport and get some fish n chips at Anthonys in the terminal. They just redid it and is a nice place to relax for a few.
