One of the few R, J or F fares from this region that has not been pulled by AA. It’s been around for a couple of months but it does seem like any exposure of these fares leads to enough bookings that they get pulled... so you delay buying at your peril.
Only one transfer allowed in C3 so that means connecting in HKG or ICN, unless I am missing an exKTM nonstop flight to another AA Asia gateway. Good fare for getting into F on HKGDFW or HKGLAX.
