With the travel I expect for the rest of the year (and also the inflated fares I expect to pay), plus the PQP I've earned with my UA cards, it's looking like I might end up in December with about 8,000 PQP and 21 PQF. Is it worth the $1,000 or so for me to try to hit Plat?

For context, I hit Gold for the first time ever at the end of last year with ~6,1000 PQP and 24 PQF. All leisure travel too. I fly a lot of SFO-DEN and other ex-SFO shorthaul, plus some transcons and 2 or so trips to Europe. I will usually try to do the transcons and Europe in J award tickets.

If I hit Plat, I suppose the Plus Points might be nice, but I'm not sure how much else my flying experience would materially change. Gold felt like a big enough step up from Silver with E+ at booking and Star Gold lounge access, but that's about it. Am I missing anything else with trying to hit Plat?
