I haven't flown Alaskan before, but I did yesterday. GREAT experience.
1) no pn served during snack service. It was some "chex mix" type snack with no blatant nuts/on (but of course a warning on the package)
2) sold snacks include tree nuts, but not many people bought (and tn smell doesn't bother me)
3) the roomiest standard coach seats I've ever been in
4) they have a 'we don't serve blatant pnts, but our sold/free stuff might contain' and CYA statement. Pretty typical and I do ok with that level of statement when flying
I'll fly them again for sure...seriously -- SO MUCH LEG ROOM in the 737!!
...not to mention the pilot who introduced himself as having 20 years experience and 15 years before that as a navy pilot. Liked the re-assurance for sure given the recent air accidents (and that Japanese Taipei one I SAW RIGHT BEFORE I LEFT FOR THE AIRPORT!!!)
Beautiful take off and landing, seriously - best landing ever! And San Diego is a SHORT runway for a 737! I'm going to tweet a thanks to the pilot, it was THAT GOOD.
