I jumpseated to Ho Chi Mihn City a couple months ago on United. No problem getting over, except for the mechanical cx that happened in Hong Kong. It would have been completely free, i.e. no tax, but since I had to stay over night in Hong Kong, I had to pay the departure tax (about $15). Departure tax was paid to leave Viet Nam. I think that was $14. I had a couple of ZED fares in my hip pocket for the trip home, as the loads were kind of iffy. I ended up on Eva Airline from HGK-TPE-LAX on the way home. Just as a side note, you (SKYW pilots) CANNOT occupy the actual jumpseat on international flights. BTW, on the flights in between Hong Kong and Ho Chi Mihn City, first class was wide open but they only put me in business class. (I say "only" with my tounge in cheek. Business class is a sweeeet ride after doin' econ across the pond.) I think that's a j/s thing with a 3-cabin class aircraft. Anywho, it was my first international j/s and they treated me great. One word of advice I got from a seasoned j/seater. . . . . . when leaving some of the . . . . . . ummm. . . . . less developed countries. . . . . as a jumpseater, it helps to be in uniform. If you try without it, sometimes they'll tell you that only pilots can jumpseat. You show your i.d. and they still don't beleive your a pilot. Of course if you're in uniform, they won't ask to see your airline id. . . .and nobody will spit on you 'til you get back to the good ol' USA.
