Qatar Airways, the state-owned flag carrier of Qatar, on Thursday said that it intends to acquire a 10% stake in American Airlines (AAL) - Get Report , which sent the stocks of major U.S. carriers higher.

Perhaps none were better positioned to take advantage of the jump than Warren Buffett's Berkshire Hathaway Inc. (BRK.A) - Get Report  , which invested billions of dollars into the U.S. airline industry earlier this year. 

Berkshire's substantial interests in the four major U.S. airlines (American (AAL) - Get Report , Delta (DAL) - Get Report , United (UAL) - Get Report , and Southwest Airlines Co.  (LUV) - Get Report ) caused his portfolio to climb $76 million on the news.

What's Hot On TheStreet

Tesla still doesn't deserve its valuation: Tesla Inc.  (TSLA) - Get Report fanboys have just gained their daily pound of flesh. The electric car company has reportedly reached a deal with officials in China to open a production facility in the world's biggest clean-energy car market. The deal would likely allow it to form a joint-venture with a China-based partner and avoid the 25% tariff applied to imported vehicles. The move would also substantially cut shipping and production costs when compared to Tesla's facility in Nevada, TheStreet's Martin Baccardax reports.

Tesla is now valued at an insane $61 billion...and counting.

What was this Kroger exec drinking: Maybe this Kroger Co.  (KR) - Get Report fella has been up too late studying the aftershocks of Inc.'s (AMZN) - Get Report big deal for Whole Foods Market Inc.  (WFM) . "I'm glad their stores are finally open," Kroger CFO Michael Schlotman said about German rival Lidl at Oppenheimer's Consumer Conference Wednesday. Schlotman said he is excited, in fact he feels "great about it," to finally start seeing if the preparations Kroger put in place to compete with Lidl will stand the heat. TheStreet's Lindsay Rittenhousewas all over this bizarre exchange.

Having your profit margins crushed by a ruthless German grocer shouldn't be exciting, Kroger.
