Thanks for the replies. I'm sorry I wasn't more specific. I haven't bought my ticket yet but I'm pretty sure I'll be flying economy. I belong to USA's and AA's FF programs and it looks like I'll fly Qantas or ANZ. I will be going out of LAX at the end of Oct. 99.9% of my flying has been on 737's. I think I was once or twice on 757's. So as you can see I'm not familiar with the big jobs.
