Now Tigner is suing United Airlines, Alejandro Anastasia -- the man who pushed him -- and another United employee for negligence. The man was left lying there motionless. HOUSTON – Almost two years ago, a pair of United Airlines employees allegedly laughed at, cursed at and even physically injured an area attorney when he asked for a new boarding pass, according to a recently filed lawsuit.  HOUSTON - For decades, United Airlines has boasted "come fly the friendly skies of United," but in April, video of Dr. David Dao being dragged off a United flight in Chicago went viral. The passenger, Ronald Tigner, a Houston lawyer, is suing United and two of its employees for more than $1 million, alleging negligence in the incident that took place July 21, 2015, at George Bush Intercontinental Airport in Houston. In response to the video, United released a statement to KPRC saying it is “disturbed by the completely unacceptable behavior shown in a video of a customer and a former United employee.” The employee is no longer with the company, according to the statement. “The actions shown here do not reflect our core values or our commitment to treat all of our customers with respect and dignity,” United’s statement read. “We are reviewing all circumstances surrounding this incident and reaching out to our customer through his attorney to profusely apologize for what occurred and to make this right.” 
 
 The encounter began when Tigner received a boarding pass that was illegible. He was told to continue on to the security checkpoint, where Transportation Security Administration authorities refused to let Tigner enter because of his poorly printed pass. Two United employees, Alejandro Anastasia and Ianthe Phillips-Allred, allegedly refused to help Tigner, laughing and cursing at him, the lawsuit states. Tigner’s attorney, William Hoke, told KPRC that when Tigner asked Anastasia for a new ticket, he replied with a smile, saying, “Can’t you see I’m busy?” 
 
 Tigner then told Anastasia to “wipe that smile off your face,” Hoke said, to which Anastasia responded with an obscenity. “Defendants Anastasia and Allred, among other things, refused to offer assistance to plaintiff, laughed at plaintiff, cursed at plaintiff … and Anastasia suddenly, unexpectedly and violently injured plaintiff,” the suit states, adding that United and its employees violated the company’s core value: “We Fly Right.” 
 
 The suit does not state what provoked the employee to allegedly injure Tigner, and only contends that nothing Tigner did caused or contributed to the incident. VIDEO: Full airport surveillance video of United worker pushing Houston passenger to ground 
 
 "This is just one of the most inhumane things I've ever seen in my life," attorney William Hoke said. After hitting his head on the ground, Tigner lies motionless with his arms splayed out and yet not one United employee bothers to bend down and talk to him. When the operator asked the employee what caused the fall and if the man was awake, the caller said he did not know. Anastasia was later charged with the felony crime of injury to an elderly individual, ordered to pay a fine, write a letter of apology and attend anger-management classes. The lawsuit alleges the confrontation caused Tigner to sustain “severe personal injuries and damages,” and incur medical expenses and lost wages. In April, Dao refused to give up his seat on an overbooked United flight and was dragged off bloodied and limp, to the disgust of other passengers who captured it on video.
– A 71-year-old lawyer is suing United Airlines for more than $1 million after an employee knocked him down during an argument two years ago, the Southeast Texas Record reports. According to the Washington Post, the July 21, 2015, incident started when the TSA at Houston's Bush Intercontinental Airport wouldn't let Ronald Tigner through due to an illegible boarding pass. According to the lawsuit Tigner filed June 7, he returned to the ticketing area. He says two United employees—Alejandro Anastasia and Ianthe Phillips-Allred—refused to help him there, instead laughing and cursing at him. Tigner's attorney, William Hoke, tells KPRC that when Tigner told Anastasia to "wipe that smile off his face," Anastasia threatened violence. Hoke says surveillance video of what happened next is "one of the most inhumane things I've ever seen." Video shows Anastasia shove Tigner to the ground, where he lies motionless and splayed out for minutes. Hoke says Tigner hit his head on the ground and was knocked unconscious and that United employees stood around looking at Tigner until a passerby finally stopped to help him. "They literally left him there like a piece of garbage," Hoke says. Tigner is suing United, Anastasia, and Phillips-Allred for negligence. The lawsuit claims he was left with "physical disfigurement" and "mental anguish." United says Anastasia's behavior was "unacceptable" and "does not reflect our values." Anastasia was charged with felony injury to an elderly individual and punished with a fine and anger-management classes. He no longer works for United. (United's new flight is a doozy.)
