Brutal... off to AA most likely for this SLC based hub captive. With the prices DL is charging here, combined with SC access getting nuked, the idea of taking a layover becomes a lot more appealing, especially since I've heard upgrades for Plat Pro on AA (which should be very doable for me given current travel patterns/spend) are a lot more consistent than for PM on DL.
Though as someone who hit PM on ~$6k of spend last year plus the Amex waiver, I'm sure I'm the exact customer they're trying to get rid of with these changes. Nicely done, DL.
