United Airlines is buying 25 additional Boeing 737 Max planes and taking delivery of other orders earlier than previously planned as it prepares for a recovery in travel demand, the carrier said Monday.

"As we plan for the future and the return of demand, we've been looking at ways to best position our fleet for the recovery and be in a position to best take advantage of people's desire to travel," Andrew Nocella, United's chief commercial officer, said in a note to staff.
