Although is purchased a seat for the flight,, JetBlue scams passengers to buy upgrade seats. When I checked in the kiosk showed only upgrade seating was available which was a lie. Even on the plane, the attendant announced upgrade seating was available for $80. That's terrible of JetBlue. My seat was very worn out and had something jabbing into my side. The televisions were all flickering throughout the flight. Unable to watch any of the programming. I tried sleeping as much as I could on the flight. Sometimes paying less for a flight is not worth it especially when the flying in this particular plane. Hopefully JetBlue upgrades their fleet so that customers in the future do not experience the same as I had to experience. Thank you for your attention. Nicholas Protopapas.
