Flying JetBlue New Mint Studio Business Class A321LR Transatlantic 

I tried out the new JetBlue Mint Business Class from LA to New York then onward to London, all the way across the Atlantic on a single aisle Airbus A321.
On my first flight from LA to New York, I was in a regular JetBlue Mint Suite. The seat was facing from window to inside the cabin. The dining concept was different and I could choose 3 plates and 1 dessert. The food both look and taste phenomenal. JetBlue has a great new product on the US Transcon market.
In New York, there was no lounge available for Business Class. I boarded my next flight to London. It was operated by A321LR with auxiliary fuel tank. The pilots explained their narrow body transatlantic operation. On this flight, I paid an extra $299 upgrade to sit in JetBlue Mint Studio in row 1. It has extra room with an extra buddy seat and table. I checked out the rest of the JetBlue product in both Core economy and Mint Business Class. At the end of the flight, I gave my verdict whether the JetBlue mint studio is worth the extra money.
