This was our first experience flying this airline and it won't be our last. First of all, the ticket price was reasonable and competitive with the other airlines. Then, we found that you can take a personal item AND a carry on without paying an extra fee. Checked baggage is, of course, more.
The flight was on time and we experienced no delays going either direction. We learned that JetBlue does not overbook their flights, so there is no drama at the gate at departure time. A FREE snack and a non-alcoholic drink are offered during the flight. There are TV screens in the back of each seat with free TV shows and movies, (you must buy the earphones though). There is also free Wi-Fi. (You may set up an account to use it.) You can pay extra for extra leg room or an exit row, if you choose, but I found coach very comfortable. (Our aircraft only sat two seats on either side of the aisle.)
Finally, the flight attendants were friendly and attentive to all.
