Good day to you Victor.
I hope you had a good Christmas, Best wishes to you and yours for the New Year.
The clip I'm attaching here has the communications between JetBlue #50 and Ground which I inadvertently omitted from the file I posted late last night.
This is the archive file containing the comms with JetBlue 669 on 26 December -

Evidently, a different case to the one which caused the diversion.
Later PS. I have listened to the arrival of #669 at Reno on diversion on 24 Dec. There was no reference to the reason for the diversion. Seemingly a normal landing.
