United Airlines will be flying its busiest schedule from Chicago this fall, with more expanded service to warm-weather destinations people love.
The airline is scheduled to fly up to 592 flights daily from Chicago O’Hare in October, more than any other time this year.
Expanded routes to warm-weather destinations make up the majority of its flight increase, with more flights to Phoenix, Austin and Orlando, along with Liberia, Costa Rica; Cozumel, Mexico; San Martin; Guatemala City, Guatemala; Punta Cana, Dominican Republic; and San Jose del Cabo, Mexico.
Many international routes to Latin America are getting expanded weekend service in either October or November.
“Building on the momentum of an anticipated-record-breaking summer, we’re taking things further this fall with our busiest flight schedule of the year — adding more flights and extending service to warm-weather destinations in the U.S. and around the world,” said Omar Idris, United’s Vice President of O’Hare. “This is truly a historic time for our hometown hub of O’Hare as we’re not only offering our customers the largest network from Chicago, but also new industry-leading amenities both at the airport and in the air.”
The airline also recently debuted its expanded Polaris Lounge at the airport, providing international business class passengers with around 25,000 square feet of places to work, dine and otherwise spend some time before, after or in between flights.
