Now we can see if there is upgrade space on DL flights and if they need a Regional Upgrade cert or a Global Upgrade Cert (like RU and SWU on United Past )
But
the GUCs no longer confirm to business - they move you to Delta Premium Economy (a bit better than Comfort Plus on long flights, with waitlist to Business (Delta One)
OK, that's an improvement at least. Thanks for that data point.
But, yes, I remember seeing the second point as well (which I would originally have said I expect UA to copy, but with the way PlusPoints works, I suspect they'll just tweak the chart instead). So, yes, you'd be looking at upgrading a PE fare vs. a Y fare. In some markets, that's (relatively) fine -- I've seen PE fares as low as $300 RT more than Y, which isn't zero but wouldn't torpedo the program entirely for me. But I've also seen PE fares that are 3-4x the Y fare...
So, again, for all the kvetching, it's one more reason I chose to stick with UA... but I'll continue to reevaluate periodically. as, IMO, everyone should.
