I had tried a number of times to get through to Jet Blue with too long a wait for me. So I called about 6:20 this morning (EST). The person was very pleasant and clearly confirmed that my fares would be credited back to my original form of payment.
I haven't checked my credit card account yet, so I don't know if this has actually happened. I'll check in a day or so and post an update.
(BTW. I might have changed these tickets to my Jet Blue credit card. )
