One week after Spirit AeroSystems announced it has "substantial doubt" about its ability to continue as a going concern, Boeing is offering help.

Spirit AeroSystems said on Tuesday it would receive up to $350 million in advance payments from its largest customer Boeing and up to $107 million from Airbus , giving the struggling supplier a lifeline as it burns cash after four consecutive years of losses.

Spirit AeroSystems said on Tuesday that Boeing will pay a total of up to $350 million in advance payments to the firm, providing the struggling supplier a lifeline as it continues to burn cash after four consecutive years of losses.

Boeing says it will be several weeks before it fully resumes building passenger planes, as factory workers return following a strike that lasted nearly two months.

Boeing said on Tuesday it delivered 14 commercial jets in October, less than half of the 34 jets it handed over to customers during the same month in 2023, after a weeks-long strike halted most of its aircraft production.

Boeing received its first order after reaching a deal with striking machinists, but it still faces a difficult road ahead.
