Maybe it's partially due to fleet age? The majority of JetBlue's fleet is made up of A320s (129 total) with an average age of 13.4 years. They have newer A321s (62 of them) which are an average of 2.5 years old, with the remainder (60) being E190/195s with an average age of 10.2 years. You might want to pay attention to the aircraft type the next time your flight goes mechanical. Odds are it will be an A320 or E190/195 as older planes tend to break down more.
