Thanks Ernestnywang for the tips about the rule.

Via Amtrak, I don't think that I should leave HKG airport because there will be 6 luggage between bf and me. It is probably easier to just stay in the HKG airport.

I am actually getting very worry about flying out dfw tomorrow night at 8:25 p.m. The weather has been bad in Dallas and many flights have been cancelled. The storm is supposed to hit again in the evening tomorrow. I guess that I will try to go to the airport early to see if I can get on an earlier flight. What would happen if my flight from dfw to lax got delay... Will CX help me with the rebooking? Hope things will go ok tomorrow.
