I think that's a bit of an overreaction. Amex Delta cardholders don't board in Sky Priority, they board in Zone 1. Only Delta Gold Medallions (and up), SkyTeam Elite Plus, and very high elites on the two Virgins and GOL board in Sky Priority. The sole difference in the new boarding order is that Comfort+ now boards after PREM. In many cases, if you are eligible to board in SKY, you will actually be eligible to board in one of the higher groups anyway.

Well, you could always fly F on MCO-LAS and board in PREM right after nearly 2/3 of the flight preboards in their wheelchairs a few hours before literally running to baggage claim.

I actually LOL'd at this, but you know you're not wrong, I often see those wheeled onto some flights flying by me on the way to baggage claim.
I'm not usually in a rush and find it fairly amusing.

Are those the "miracle flights" I've read so much about?

B you beat me to it, lol!
You do realize why they are doing this? Revenue. If you buy ComfortPlus, you have paid more than someone just working status in Steerage.
If you want to jump the line, it’s easy. Buy the upgrade to Comfort Plus or better yet First Class.
And the credit card boarding is the same place in line.

Agreed. Revenue upsells are a huge source of income for Delta and other airlines (or air lines as Delta chose to put it). I've done it a number of times, and with the ability to easily upgrade with miles and earn MQMs on the fare class actually flown, I'll be more likely to self-upgrade to F, even if I was reasonably confident that I would get the free upgrade anyway. Comfort+ is similar to other fares like Virgin Atlantic's Economy Delight that gets some extra perks without truly being a Premium Economy fare. If someone's going to pay $35-75 or more each way to put themselves in a C+ seat, I'm fine with them boarding ahead of me no matter what my status or what cards I hold.
Let's be honest, once it gets past F passengers, the real reason most people want to board earlier is to secure overhead bin space. If you're boarding in at least Zone 1 or 2, it's not going to be an issue. If you're Sky Priority and not flying C+/F/D1, you're still going to be one of the first ones boarding in the Main Cabin.
