It's great to see the results of our efforts have paid off - it's sad however when you have very long term 20+ year Delta only flyers, like me, who have already left.
Unlimited upgrades are nice, but better at time of booking for any fare class (which is what I get at United), and full EQM credit for any fare basis paid (still 0.5 for LUT fares on Delta). And United's SWU's are now applicable to every international fare except S and T (Like Delta's U and T's). That saves me a lot of money on my international flights.
I UPGRADE EVERY FLIGHT I TAKE ON UNITED THE DAY I BUY THE TICKET. Period. Just like I used to do on Delta. Delta had me paying "K" or better. Now I don't even have to do that. I would have never looked at other carriers if it hadn't been for Delta's changes. Knowledge is irreversible.
