HOLLISTON, Mass. - A retired flight attendant is walking from Boston to New York City in an effort to bring more recognition to the men and women of four flight crews who lost their lives on Sept. 11.

Paul "Paulie" Veneto, 64, first made the trek in 2021, traveling more than 200 miles while pushing an airline beverage cart. "Paulie’s Push," as it came to be known, spawned viral TikTok and Instagram posts, as well as an appearance on TODAY.

“The idea first came a year after 9/11, I thought about pushing the beverage cart,” Veneto said. I knew I needed to do something that would draw national attention. I had no idea what I was in for, how could I?”

Veneto has always worried the legacy of the four flight crews aboard American Airlines Flight 11, American Airlines Flight 77, United Flight 93 and United Flight 175 would be forgotten. Veneto himself frequently worked Flight 175, including the night of Sept. 10, 2001.

“The guys that I knew, the crew on that plane, I loved every one of them when I worked there,” Veneto said. “They were professionals, they really were. I wouldn’t want to be with anyone else if I was under those conditions, and I’m not just saying that, that’s the truth.”

He often talks about his co-worker Amy Jarret in particular, a younger flight attendant who was working on United Flight 175 when a hijacker slammed the plane into the World Trade Center.

“I worked with her a lot in the back of the plane,” Veneto said. “She was only 28 years old, but I knew the whole time when I was working with her that everything was going to be alright up there. I could always count on her.”

The top of Veneto’s beverage cart includes the names and photos of Jarret and more than a dozen other crew members who lost their lives on 9/11.

He plans to arrive at Ground Zero in Manhattan on Sept. 11, this year in memory of American Airlines Flight 11.

His initial trip in 2021 followed a similar path, and he followed it up with a trip from Dulles International Airport to the Pentagon in 2022 and a trip from Newark Liberty International Airport to the National Flight 93 Memorial in Shanksville, Pa. last year.

Initially, he had only planned one "Paulie’s Push," but Veneto shows no signs of stopping.

“A lot of us that were close to these crews that were based in the cities these planes were taken out of, it hit us hard,” Veneto said. “Of course it did. That’s why I do it, these people are American heroes. They deserve us all to recognize them.”
