JetBlue Airways stock could gain ground as the carrier attempts an overseas expansion, some CNBC "Fast Money" traders said.

The company on Monday said it is looking into extending its network to South America and other places abroad with a long-range plane from Airbus. JetBlue closed Tuesday barely higher.

While he was disappointed by the way it traded after the news, trader Guy Adami said he still likes JetBlue at its current price, below $20 per share. The stock has climbed more than 20 percent this year, and trader Steve Grasso agreed that he would stick with it, especially after a recent pullback in the wider airline sector.

That broader weakness has brought Delta Air Lines to "interesting levels," said trader Tim Seymour. The stock has fallen more than 17 percent this year, and closed Tuesday around $40 per share.

Delta looks risky if it fails to hold above $40, he noted.

Boeing looks the most appealing in the aerospace sector, trader Brian Kelly contended. The stock has climbed almost 10 percent this year.
