It does seem to be a better option if flying economy in a way. I would rather connect at DFW than LAX as a general rule every day of the week (especially when arriving in the USA), and AA has many more services to many more airports/markets than from LAX. The A380 would likely be better in economy than the 747, but both flights are long affairs (and I just flew SQ 21 a couple of days ago, I have some inkling about long flights ). In my mind if flying economy, I want to get from point A to point B as absolutely quickly and painlessly as I possibly can. DFW works better than LAX for almost all origins east of the Rocky Mountains in this regard for sure.
