I’m curious about that too given that the waiver looks like it only allows for rebooking to SFO at another time/flight (not sure how that really helps given that the airport faces constraints almost 24 hrs/day) and doesn’t seem to allow flexibility to fly to co-terminals of SFO. Will be interested to see if anyone is able to do that with the waiver.
"
(UPDATE) On Tuesday Sept 10, Delta updated its policy regarding SFO flights. A spokesperson said Delta will work with travelers with SFO reservations to switch flights to OAK or SJC any time before Sept 27 with no fee and no fare difference. It also will work with passengers to postpone trips from today until Sept 27 without a fee or fare difference..." https://www.sfgate.com/travel/articl...o-14425016.php
I kept my SFO departure but switched my connection out of SEA to a later one (my choice to do it that way), waiver applied, no additional costs, C+ upgrade received. As I mentioned in my previous post, this is all in flux atm, not all agents have the very latest info, but mine was very proactive and took care of us.
