As Gale documented his escalating feud, his Twitter feed went viral. According to Buzzfeed, he had 35,000 followers on Twitter when the flight began, but quickly gained many more and now has more than 140,000 followers.
Many of his followers, old and new, appeared glued to his feed as he landed and the fight escalated from notes to alleged assault.
Gale wrote that the woman was so infuriated by his final note, she hit him.
She walked right up to me and slapped me immediately in the face— elan gale (@theyearofelan) November 28, 2013
The gate agent for the next flight actually grabbed her and held her back. He asked me if I wanted to have the airport police come over— elan gale (@theyearofelan) November 28, 2013
Gale declined to talk to police about the alleged incident.
She turned to the gate agent and said "Am I going to make my flight to Sacramento?"— elan gale (@theyearofelan) November 28, 2013
The woman did not make her connection.
But Gale did give the woman a final note, this time with his Twitter handle, @Yearofelan.
"Look me up online. Read every tweet. Read every response. And maybe next time you'll be nice to people who are just trying to help," Gale wrote.
While Gale had plenty of support from online followers, after his story went viral others started to criticize him for escalating the situation.
After his flight, Gale took to his blog and said he was especially bothered when the woman was complaining to the flight attendant.
"I know I can come across as abrasive. I know I can seem harsh. But what I've never done is be unkind to a person in a service position," wrote Gale, before writing about his work history at a video store and as a caterer. "I don't care what's going on with you: Don't be rude to people who are doing their job."
Gale was not immediately able to be reached for comment.
US Airways said it was investigating the possible incident and talking to crew members, but could not yet confirm anything from Gale's Twitter feed.
Editor's Note: On Monday, Elan Gale tweeted a photo of an empty chair, and apparent acknowledgement that his alleged "note war" with another airline passenger and the ensuing altercation referred to in this story, was a hoax. Gale has not responded to ABC News' requests for comment..
