it same as the Airbus A320 some have gained winglets similar to the NEO's again certain age etc etc
also cost of fitting,
There is a reason FF & FJ never got the blended winglets, even had an engineer tell me but.... 🙈 I've forgotten. However, its not necessarily vintage/line number that is the reasoning. Note FD is one of the oldest -800s still operating in the world and has winglets. Not sure it will be arround long enough to get the scims mind.
