My biggest take away was the people, they all (at least the ones I interacted with) seemed to be genuinely happy and wanted to provide good customer service. While I was in the gate area an Asian Woman who did not speak English went up to the counter and handed over a piece of paper with some writing on it and the Asian lady pointed at one particular line.

The Employee read the line and then asked one of the Flight Attendants in the gate area if she would show the woman where the restroom was as she did not speak English and could not find it on her own. The Flight Attendant took the Asian Lady by the hand and escorted her to the restroom and even tried to use a few words of her language (Chinese). She then used her phone and some sort of translation software to compliment the passengers scarf, which made the passenger smile. I once watched a UNITED Employee deal with a similar situation and her solution was to yell at the customer, tell him we are in American and should speak English and then get frustrated when that did not work and her final solution was just to walk away, leaving the passenger to fend for himself.

Again, my biggest takeaway where the people, I will remember them for a long time to come.

Truth be told I did not have an expectation of JetBlue, I did have an expectation of a Premium Product and their Premium Transcon product did not check all the boxes for me, but as you said, "travel is about creating memories" and over the top service, be it positive (in the case of JetBlue) or negative (in the case of UNITED) does last (again as you said and I completely agree) a lifetime.

I was talking with a colleague who was from NY and flew JetBlue when he lived there (though never on their Premium Transcon Product) and he said JetBlue is about NY and thus maybe why I missed some of their references to NY (The Ice Cream Company, The Featured Restaurant, etc.) I never really spent any time there.
