ORD-HKG on AA thru LAX or DFW? (which best for upgrade)
Thinking about doing a mileage run from ORD to HKG either thru LAX or DFW. Fares are pretty low, around $800 and I'm flexible on dates. I would book economy but use SWU for the trip, so I was wondering if it's best to fly thru DFW or LAX? Which one has higher chances to clear? Any reason why to pick one over the other?
