Alec Baldwin just can’t let go of the rage.

The hotheaded actor lashed out — again — at American Airlines and a fellow flier yesterday.

Baldwin, using The Huffington Post as his mouthpiece for a second day after shutting down his Twitter feed, dissed passenger Steven Weiss, who said he witnessed the “30 Rock” star get kicked off a flight in LA.

The actor had refused to turn off his cellphone, even after the plane’s doors were closed on Tuesday.

“Three things I think are worth mentioning here. One is that American Airlines’ ‘source,’ a Mr. Weiss, is a liar,” Baldwin wrote. “I never talked on the phone.”

Baldwin insisted he was just wrapped up in an online game of Words with Friends while waiting for Flight 4 to take off as other passengers also played with their gadgets.

“Why do I believe I need to be treated differently from other passengers?” Baldwin wrote.
