JetBlue Airways Corp.

Discounter JetBlue Airways Corp. reported its first full-year profit in three years and its shares soared on the news that it is negotiating with Deutsche Lufthansa AG over a "commercial agreement" which could include booking passengers on one another's planes. The German airline recently paid $300 million for 19 percent of JetBlue, giving the Forest Hills, N.Y., carrier the much needed cash but so far no code sharing arrangements.
