TOKYO: Shares in Japan Airlines (JAL) surged 31 percent yesterday after the Japanese government came up with additional financing for the troubled carrier.

Separately, Japan Airlines and alliance partner American Airlines denied local media reports that said JAL had chosen Delta as its new partner.

Japanese transport minister Seiji Maehara told reporters Sunday the state-owned Development Bank of Japan will double its credit line for Japan Airlines Corp to 200 billion yen ($2.2 billion).
