If I posted every GPU failure, I would crash this website. As a 1K for as long as I can remember, I have rarely had GPUs, and even RPUs, clear. I currently have 6 flights (mix of intl & dom) waitlisted for GPU/RPU - all requested at time of ticketing - and I have no expectation that any will clear because it has been so rare that they do. I have even tried GPUs on LH and NH on J-fares months in advance to no avail. On intercontinental flights, my company flies us in business class so for work travel I only had a chance to try to use them when I got stuck on 777-200 - and I never had one clear. I flew on a 777-200 two days before UA announced the end of Polaris First. My flight was originally on a new Polaris aircraft IAD-BRU but it got swapped last minute for 777-200. UA would not take a GPU but gladly took $500 & some miles to get to Polaris First. I am sitting on 8 RPUs and 10 GPUs right now but at this point they feel worthless--and if the 6 flights don't clear they will re-deposit. It's hard to see them as a benefit when they never clear.
