Jim Stanek, a disabled veteran and Paws and Stripes cofounder, claims United Airlines staff physically abused his service dog, Sarge, and verbally abused him during an unexpected three-day layover at Dulles International Airport outside of Washington, D.C.
In a video posted to YouTube detailing the abuses, Stanek says the "nightmare" began on July 15, while he was at the ticket desk.
"Some United Airlines employees were moving by and one of them was startled, turned, and kicked my service dog," Stanek says in the video. "Didn't kick her hard, but ... they kicked her."
Stanek continues, saying he chalked it up to an accident and let it go -- even when it happened a second time by a different United staffer.
The Daily Mail reports Stanek has post traumatic stress disorder (PTSD) as well as traumatic brain injury (TBI) following three tours in Iraq, which makes standing in loud crowds and reading difficult. In the video, Stanek states the most traumatic part of the ordeal occurred when, while trying to get a hotel voucher after his flight was canceled for a second day in a row, the man at the ticket counter asked if he was "retarded" -- referring to his inability to stand in the line with everyone else, and read the paperwork.
"I completely lost all composure at that point," he said in the video. "I started yelling, I used four letter words ... and I've worked very hard not to be like that."
According to the blog Reduced Mobility Right, the U.S. Department of Transportation has opened an investigation into the incident, with the cooperation of the airline.
"We are reaching out to the customer directly to discuss the events that he described," a spokesperson for United told Reduced Mobility Rights on July 21.
