I'm traveling with a bunch of colleagues who are kettles on DL. I'm a DM and hooked them up with C+ seats. I have an opportunity to use a RUC to be upgraded, but, as mentioned in another post, I have to split my reservation so that I have my own PNR. I originally put my colleagues under my reservation so that they'd be more comfortable. That being said, because we're flying across the country, it'd be nice to get upgraded and burn a RUC. Obviously I don't want to come off as a jerk and possibly leave everyone behind. Then again, they decided to fly under my name so that they could get C+, even though they would get home an hour later than the other flight that my other colleagues are on. I did get them better seats, better snack selection, free booze, etc.

What would you do? Should I split my PNR, and pray that there's no equipment change? That way, they remain in C+? Or, should I keep my PNR as is and basically be resigned to sitting in C+ with zero shot of an UG? I'd appreciate whatever collective wisdom you FTers might have.

(For what it's worth, I talked to a DM agent, and she said that because my colleagues' tickets all show "$0.00 balance" for C+, they should be able to remain in C+ even if there's an equipment or schedule change. If the routing changes (e.g., LAX-ATL-DCA to LAX-DTW-DCA), however, all bets are off because the cost of C+ is based on distance.)
