United Airlines said on Wednesday it has entered into an agreement with Boeing on compensation of financial damages incurred in the first quarter due to the grounding of 737 MAX 9 aircraft.

US regulators had in January grounded some Boeing 737 MAX 9 aircraft for safety checks following a cabin panel blowout in a new Alaska Airlines jet.

The compensation provided by Boeing for the grounding damages and in connection with rescheduling deliveries is in the form of "credit memos" for use on future purchases from Boeing, United Airlines said.
