By all accounts, this was a good year for business. Wall Street enjoyed the best year of IPOs since the tech crash in 2000, the Dubai economy bounced back and the Qatari royal family now owns more of London than the Crown Estate .

But it wasn't all roses and sunshine. Here were the biggest business blunders of 2014... Take note. From getting kicked off plans to trash talking Mark Zuckerberg, these are great examples of poor behavior, by our so-called business leaders.

1. Don't throw a tantrum on the runway.

Korean Air Flight 86 was ordered to turn back around to the gate when passenger Cho Hyun-ah, who also happens to be the daughter of chairman who runs the family-owned Korean Air congolmerate, ordered a flight attendant to be kicked off of the plane, after the way she served nuts. She is also, not surprisingly, the head of in-flight services for Korean Air. Although she has subsequently resigned, Korea, and the world, will not let this story go as it is a prime example of aristocracy in South Korea. Many South Korean even went so far as to boycott the airline, dubbing it "Air Nuts".

2. Keep your rants about coworkers off of your company email.

In addition to $100 million being lost, Sony's leaked emails revealed that Hollywood producer Scott Rudin called Angelina Jolie a brat. Ooof.Sony executive Amy Pascal said that Adam Sandler was an asshole, in addition to thinking his movies were tanking the company. The leaked emails also highlighted a very combative fight between Pascal and Rudin, over the Steve Jobs movie, which thanks to their fighting, will not be made by Sony Pictures.

One plus? Actor Channing Tatum wrote this hilarious email about 22 Jump Street's success at the box office. He seemed to be the only winner in this business blunder.

3. Don't let your top talent resign.

Former Yahoo Co-Founder Jerry Yang was vindicated this past year when Chinese e-commerce site Alibaba had a record-setting IPO, raising $25 billion when the stock debuted on the New York Stock Exchange. Under Yang's directive, Yahoo invested in this fledgling company in 2005 for a mere $1 billion. That's a huge return on investment, for someone who was widely criticized by shareholders prior to his resignation from the company in 2012.

4. Don't go Wolf of Wall Street on the plane.

This December, two Blackberry executives - George Campbell, 45, of Conestogo, Ontario, and Paul Alexander Wilson, 38, of Kitchener, Ontario - boarded an Air Canada flight from Toronto to Beijing and proceeded to get positively toasted in air. And while many people enjoy a glass of wine when they are mid-flight, these two took it a bit too far when they ended up in restraints and made the airplane emergency land in Vancouver. We don't know what they were drinking, but we'd like to try a few glasses ourselves.

5. Never lie to the media... especially if it's about Mark Zuckerberg.

In early January, Snapchat's CEO Evan Spiegel originally claimed in this Forbes cover story that he turned down Mark Zuckerberg's invitation to Facebook in San Francisco, saying that he told Zuckerberg to visit him in LA. But, when a Business Insider article called him arrogant, Spiegel outed himself as a liar on Twitter, admitting that he misrepresented their exchange.
