thanks everyone! i just drop the idea of staying in the airport overnight. maybe i should just get a LONE5 instead of DONE5.

Too bad! I can't make MEX-DFW-ANC-DFW!! ANC is in the middle of my route (the 10th destination).. while my trip runs from Jun07 to May08, I should be arriving the North American continent sometime in Oct/Nov. Can't put Anchorage in Jun-Sep... I am thinking to add SEA into my xONE5, then i can get flights to Anchorage or Fairbanks operated by Alaska airlines...

so here comes a revised routing:
HKG-AMS//RAK-MAD-CAI-BCN-JFK-CUN//MEX-DFW-SEA-DFW-LAX-SCL-IPC-SCL-MPN-PUQ//SCL-SYD-AYQ-CNS-HKG

There are only 19 segments here, still get 1 left.

Can I really have SEA-DFW-LAX? I can't find any connections for SEA-xxx-LAX with the Oneworld timetable software, so really not sure if it can work or not. Also, I do not put any transcontinental flight between east and west. Is it alright for that?
