As a DL elite plus flyer, you probably will not even be noticed for an operational upgrade. As a NW plat and gold, I like JPDX have gotten a number of them. The last was in November traveling with my Gold level wife out of PDX. They were oversold by 7 in coach, I volunteered to let them let us sit in business class and we received boarding passes for that class. Guess you could call this a Platinum companion trans-pac upgrade.

Other than this point, I agree totally with JPDX. (Well, maybe not about the seats since this is a hidden benefit-if you are in one of my seats, you have to move.) LOL

The closest that you can get to PNH on SkyTeam is Bangkok. You can get to SGN on AF, but the lowest fares now only earn 25% eqm. It is cheaper to fly BKK-PNH on AirAsia than any other routing. Another approach is to route thru SIN on NW and use someone like Tiger to get to PNH. This yields more eqm than BKK but means a longer flight from the SIN than from BKK..
