Spirit said this week it is seeking ways to raise liquidity including possible customer advances. The supplier has previously disclosed it has drawn down a $350-million bridge loan set up when Boeing agreed to acquire the supplier, and previous advances from both the U.S. planemaker and rival Airbus that Spirit has not repaid.

Spirit AeroSystems (NYSE:SPR) edged higher by 0.3% after a report that the struggling supplier is close to reaching a funding agreement with Boeing (BA) that would give it a cash lifeline. A deal may be announced in the next few days,
