It’s been a week of “firsts.” We are the first U.S. airline to publicly commit to reduce our greenhouse gas emissions — 50% by 2050. Now, UA44, from San Francisco to Zurich, is the longest transatlantic flight to date — and the longest by a U.S. airline powered by a biofuel volume of this size. Check out our story to learn more about this history-making flight & our goal to be the most environmentally conscious airline in the world. #EcoSkies #StepUp2018
