Alec Baldwin boarded an American Airlines flight from Los Angeles to New York City yesterday afternoon, but got booted from the plane before takeoff.  Why?  Because he was playing "Words With Friends"

For those of you who don't know, Words With Friends is basically Scrabble for your smart phone.  You can also play it on Facebook.  You can play it with people you know or hook up with random opponents.

As you may know, airline passengers are required to turn off all electronic devices during takeoff and landing.  But since the plane hadn't even begun taxiing yet, Alec thought it was cool to keep playing.  He was wrong.

Alec Tweeted,

"Flight attendant on American reamed me out 4 playing WORDS W FRIENDS while we sat at the gate, not moving. #nowonderamericaairisbankrupt."

He added,

"But, oddly, 30 Rock plays inflight on American. #theresalwaysunited."

Another passenger Tweeted,

"On an AA flight at LAX.  Alec Baldwin removed from the plane.  We had to go back to the gate.  Terrible that everyone had to wait."

TMZ claims that it was the pilot who yanked Alec from the plane, but not just because of the game.

A source says that after Alec's altercation with the flight attendant, he got up to use the bathroom.  And he slammed the lavatory door so hard, the captain heard it.  So he made the call to boot him.

Alec was re-booked on a later flight, but he still wasn't happy about it.  He Tweeted,

"Last flight with American.  Where retired Catholic school gym teachers from the 1950s find jobs as flight attendants."

Alec Baldwin has since deactivated his Twitter account

Here's what Alec's rep had to say about the incident: "Alec was asked to leave the flight for playing Words With Friends while parked at the gate.  He loves WWF so much that he was willing to leave a plane for it."

American doesn't want to lose Alec's business.  The airline already Tweeted that they're looking into the incident, and they want him to give them his side of the story.
