I'm thinking this helps me. I had two non-stop flights scheduled on Delta to LAX and back for in a couple weeks. I've cancelled everything else associated with this trip but had held off on cancelling my flights since the original offer was just a credit that had to be used before the one year mark of the purchase of the ticket, which would be this October. In the past month, my 2 non-stop flights were cancelled and I've been switched flights multiple times. As of now, they have me on flights with two stops out to LA, both of which note that the connection times are so tight I might miss the connections, and flights with one stop on the return.
I received an email over the weekend, offering me a credit good until May of 2022, if I cancelled. That sounded a lot better so I was going to do it. When I went onto their website, I was presented with an option to request a refund, but whenever I checked that option, it told me it couldn't process a refund and to check back later. So I just didn't do anything. Now, thanks to this, I'm going to call and request my refund. It's almost $800, so I'd rather have that than a credit for later.
Thanks for posting this!
