Sunday: Los Angeles

LAX is more multicultural than DFW, both in the mix of people you see and in the languages of the public announcements.

DFW is cleaner.

DFW has free wifi available; in LAX you have to buy it or, as I did, do without.

The people in general seemed friendlier in Dallas, although the TSA people in both places were fine, and of course the Qantas people in LAX were friendly as they always are.
