South African Airways is in talks with lenders including Standard Bank Group Ltd. and Investec Ltd. about funds to alleviate a cash crunch brought on by persistent losses and a week-long strike, according to people familiar with the matter.

Negotiations are also taking place with Absa Group Ltd., Nedbank Group Ltd. and FirstRand Ltd.’s Rand Merchant Bank, said the two people who asked not to be identified as the discussions are private. The state-owned company aims to raise enough money to pay salaries, fuel its planes and cover other costs until March 2020, they said.

The banks all declined to comment.

SAA’s bid to obtain more loans isn’t assured, even if it secures state backing. When the carrier tried to raise the money needed to ensure continued operations for at least 12 months and to finalize financial statements for fiscal 2018, “lenders were not willing to extend facilities even on the strength of government guarantees,” it said in a document presented to lawmakers on Monday.

“The hesitant and inconsistent approach to addressing the recapitalization of SAA has made it difficult for the board to conclude on its going-concern status,” the carrier said.

SAA last made a profit in 2011 and has failed to implement numerous turnaround plans. The carrier delayed publication of its financial statements for the year through March until its status as a going concern is assured—a contingency that will hinge on it securing more working capital.

The airline has received 57 billion rand ($3.9 billion) in bailouts since 1994 and Finance Minister Tito Mboweni has been reluctant to give it more money or provide guarantees to enable it to raise more debt, saying it isn’t viable and should be shut down. Public Enterprises Minister Pravin Gordhan has said SAA will keep flying and a “radical restructuring” will be undertaken to ensure its financial and operational sustainability.

SAA’s acting Chairwoman Thandeka Mgoduso confirmed the carrier’s executive committee is engaging unidentified lenders, the Treasury and Department of Public Enterprises to secure the 2 billion rand it needs to pay November salaries and other creditors. The matter remains unresolved, she said in a Nov. 25 letter to parliament’s public accounts committee.

Gordhan’s spokesman Sam Mkokeli, and Mboweni’s spokeswoman, Mashudu Masutha-Rammutle, didn’t answer calls to their mobile phones seeking comment.
