When APB launched their Scimitar winglet retrofit program, they picked up a number of customer pretty quickly. I was soon seeing them fitted across the 800 and 900 series 737s of a number of operators. United and Alaska both seem to have gone all in pretty quickly. However, I guess the 700 series jets were not such a high priority – maybe the business case is not as compelling. Consequently, I hadn’t seen them fitted to any 700 series jets until I came across this United example. It was the first I had seen in action. I still haven’t seen many so I wonder whether this is going to be a fleet fitment or if United are testing it on a few airframes before making a larger decision. Anyone know?
