Embraer and Republic Airways Holdings Inc signed a contract for 47 E-175 jets, with an option to acquire an additional 47 aircraft. The new aircraft will be operated by Republic under AMR Corp’s American Eagle brand.

The deal awaits court approval due to bankruptcy proceedings at American Airlines.

The new planes flying in the American Airlines network will be the first to receive a series of mid-generation upgrades, including new wingtips and other aerodynamics to boost fuel efficiency by 5%.

With the addition of 2.05 million new domestic subscribers to Netflix Inc (NASDAQ:NFLX)’s video streaming service the company posts a surprising quarterly profit renewing investors’ faith in the company’s aggressive expansion plans.

But Netflix fell short of reaching its goal of gaining 7 million U.S. customers in 2012, missing it by 1.52 million, but its surprising profit of $8 million in the fourth quarter proved the company can still make money even as it spends heavily to acquire new content.

Shares of Netflix Inc jumped by $43.60 or 42.22% to $146.86.

The spending on new films and TV shows was accounted for its betterment by Chief Executive Reed Hastings who said “What propels our growth is that continuing content,”  “We’d like to get more movies, we’d like to get more prior-season television, we’d like to have more originals.”

JPMorgan analyst Doug Anmuth upgraded the company’s stock to overweight saying “Netflix is a primary beneficiary of the shift toward mobile devices,” “We believe the proliferation of tablets–especially low end devices with greater portability and more attractive price points–has led to incremental viewing for Netflix subscribers and improved the overall accessibility of the service.”

The Wall Street Journal reports that the company signed a deal worth $300 million with Walt Disney in December. The deal proved Netflix’s intent to compete seriously against pay-TV channels likeTime Warner’s HBO and Starz.

“Today in the United States, Amazon Prime’s content has started to be mostly a subset of ours and is,” Mr. Hastings said Wednesday. “I think over time there’s a pretty good likelihood that we’ll compete like we compete with HBO. That is, we’ll all have different shows and all be competing for dollars and attention, but not have the same content.”
