United Airlines is expanding its order of Boeing 737 Max airplanes and taking some deliveries sooner as it ramps up for an anticipated increase in travel demand.

Chief Operating Officer Andrew Nocella said in a memo on Monday that the company placed an order for 25 new 737 Max aircraft for delivery in 2023. United has also moved up delivery of 40 previously ordered 737 Max planes to next year and five 737 Max to 2023. That’s in addition to the 24 737 Max aircraft the company is already set to receive in 2023.

“We’ve now put ourselves in a position to not only survive the crisis, but thrive as an airline, elevate our product for customers and emerge as a stronger, better United Airlines,” Nocella wrote.
