Just this week, I booked a round trip to MEL and cleared GPUs at time of booking. Not only was there R space on the 787, but my connecting legs to YVR all cleared into R at time of booking. That's 5 flights (I'm connecting through SFO and LAX on the way down) with two GPUs at time of booking. I've not had that happen in 2014, or 2013 come to think of it.
