OK, thanks for the link.

Of course the email from Jet Blue that I got about the cancellation of my flight mentioned Covid, which I was sure at the time was bullsh*t, and of course, it was. Nothing to do with Covid at all. It's convenient to blame Covid when in fact you are just too d*mn cheap to honor reservations already made. I wasn't likely to fly Jet Blue any time soon anyway, but this seals it for sure.
