I agree with this. I mostly fly for leisure and got to Plat that way, so the J upgrades are of little use to me. When the Flex fare is only $50 cheaper than booking the J fare outright, without the hassle of calling for the upgrade, it feels like a false 'benefit' to me when I would just pay for the J fare outright to save the hassle and uncertainty.I just wish VA2 would do something to make Platinum more worthwhile compared to Gold.
For me personally, the upgrades to J are now more hassle than worth and the rest is just crumbs, I don’t personally care about economy X seating for all the short hops I do enough to bother.
I heard that during COVID (before I was WP) that they were allowing the upgrades on Choice fares. I would prefer to see that reinstated. That would feel more like a true loyalty benefit. The current setup only benefits people who presumably have their workplaces pay their Flex fares for them.
