United Airlines will receive compensation from planemaker Boeing for financial damages incurred in the first quarter due to the grounding of 737 MAX 9 aircraft, the carrier said on Wednesday.

U.S. regulators had in January grounded some Boeing 737 MAX 9 aircraft for about three weeks for safety checks after a cabin panel blowout on an Alaska Airlines-operated MAX 9 jet.

The incident had forced United Airlines — a prominent Boeing (BA.N), opens new tab customer — to temporarily suspend service on all 79 of its 737 MAX 9 aircraft, which resulted in a $200 million hit for the airline in the first quarter.
