Lucky to be upgraded to Jet Première ( Business class) when I checked in just before the check-in closed. A separate queue for Premiere passengers, so boarding experience was hassle-free. Welcomed by smiling crew on board, provided with a complimentary drink just after boarding. Hot towel was served. Since IFE doesn't work on domestic Jet Airways service, only flight info like fight map, distance from destination, etc were shown on the seat-back screens. A decent meal was served, with beverage options ( varieties of tea or coffee) and a dessert ( apple tart or fruit salad) . Seats were in alternate 2x2x2 and 1x2x1 arrangement in Premiere class ( 34 seats in total, on A330-300) . I was allotted the window seat ( 3A) of 1x2x1, thus having aisle access as well. Seats can be reclined to 180° lie-flat beds. I did have a small 15-20 mins nap on a flight duration of 1 hr 40 mins although blanket was provided to those only who specifically asked for. Overall I enjoyed the Jet Première class to the fullest.
