United Airlines flies with new, fuel-efficient split scimitar winglets

20 February 2014

A United Airlines Boeing 737-800 aircraft freshly retrofitted with new split scimitar winglets took to the skies this week, marking the first commercial flight worldwide to operate with the advanced winglet technology.

United flight 1273 on Tuesday took off from the airline´s Houston hub and flew to Los Angeles. The airline installed the innovative winglets on the Boeing 737-800 after the FAA approved the technology made by Aviation Partners Boeing earlier this month.

This new winglet design demonstrates significant aircraft drag reduction over the basic blended winglet configuration United uses on its current fleet. Using a newly patented design, the program retrofits United´s Boeing Next Generation 737 blended winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped scimitar winglet tip cap and by adding a new scimitar-tipped ventral strake. The new design will reduce fuel consumption by up to two percent per aircraft.

United Airlines is a unit of United Continental Holdings, Inc. ( (NYSE: UAL). For more information, visit
