The Skift Airline Innovation Report is our weekly newsletter on the business of airline innovation. We look closely at the technological, financial, and design trends at airlines and airports. Brian Sumers writes and curates the newsletter, and we send it on Wednesdays. You can find previous issues of the newsletter here. Among U.S. carriers, United Airlines has been the most daring with its route network in recent years, adding flights to far-flung destinations.
