Does NW allow different CoS on same PNR?
 

I'd appreciate if someone could answer this quickly as I have to be at the airport in < 4 hrs.

The 2 of us are travelling on one NWA.com-sold KL metal PNR. One WBC seat has come free and I'm hoping to UG using miles at the airport (outsourced ground handling but they can do it). If only that one seat is available, would it be possible to UG just one pax on the PNR or would it have to be the both of us or nothing? Just wondering whether I should have NW split the PNR now or later.

Thanks for speedy replies

Yes, you are allowed to upgrade only one of two pax on the PNR at your discretion when using miles.

Yes, but the PNR must be divided first. Only one class of service is allowed for each flight segment, and applies to all people in that PNR. The person who is changing to a different class of service (Z instead of Y, or U instead of B) must be split off and put in another PNR by themselves.

Another note to add to this situation: the OP was not clear when he/she stated that ONE WBC seat had opened up. Did he/she mean one seat opened up for an upgrade, or that there was now one seat available and all of the rest were already filled? Most assuredly, if there was one WBC seat left on the entire plane, it would NOT be available for a mileage upgrade, but would be held open for sale until the last minute, in hopes of some passenger showing up with thousands of $$$ and an immediate need to buy a ticket on that flight. On the other hand, if there were several empty seats and one had suddenly been converted to a mileage upgrade seat, then there are a lot of possibilities! A passenger with Elite Status just "might" be able to get another seat opened up for a mileage upgrade also, in order for both him and his companion to upgrade with miles. You have to ask the right questions when speaking to the right person, but this can and does happen all of the time! Best chances, of course, are when there are a LOT of empty seats and when the departure time of the flight is imminent. Further considerations are how high your Elite Status is, and how high is the fare that you paid.

If you don't ask, you will never know what might have been possible!

I didn't get a chance to test it yesterday as WBC was booked full and everyone booked apparently showed up. One revenue seat (all WBC inventory buckets except D) showed up just before I posted the message but disappeared. I think there may have been up to 5 WBC ticket holders who elected to sit in the back rather than come back the next day (today Saturday) (last-minute award WBC seats were even available!)
