JFK-SFO went out full in Y and J today at 7:30 AM. Upgrade cleared right at the 100 hr mark. FA was "strongly suggesting" that everyone needs to start pre-selecting meals now too. And she was greeting some passengers as "premium customers" and then there were thanks to EXP's. Others just were greeted by name. "Premium Customer" must be CK. F only had 4 people... Didn't appear that anyone was rolled into F either.
