Low-cost airline JetBlue Airways  (JBLU) - Get Report  may be getting ready to start a trans-Atlantic service, according to a report from CNBC

An announcement of the plans, which apparently have been in the works for the past three years, could come as soon as Wednesday, although the report said the company declined to comment. 

News of the possible entry into the long-haul international market from the U.S. East Coast to Europe excited investors with the stock jumping nearly 3% in after-hours trading Tuesday following the CNBC report. Over the past year the stock has lost more than 15% of its value.

Part of the JetBlue offering likely would involve its business class service, named Mint, which features suites for some passengers as well as seats that go flat, the CNBC report stated

The lucrative long-haul routes between Europe and the U.S. attract competition from major U.S. carriers such as American Airlines Group (AAL) - Get Report as well as those based in other countries such as British Airways and Air France-KLM (AFLYY) .

JetBlue shares rose 2.5% to $16.74 in trading Wednesday.
