I waitlisted with RPU / GPU on both segments of a round trip for four that I booked around January or February. Split the PNR a while back and immediately cleared me and my wife on the outbound. Got a computer note a few days ago that let me know tht my wife and I had cleared on the return. Still hoping the kids can clear on one or both segments.
But based on the above, the 'puter was doing its job. Having said that... I'm still checking periodically for R inventory...
