Those and other changes, which the airline called "substantial," are the result of a two-week internal probe of the April 9 incident, video of which went viral.
Passenger David Dao was pulled from his seat and dragged off the full plane by airport security in Chicago to make room for airline crew.
The 69-year-old doctor suffered a concussion, and a broken nose and teeth, according to his lawyers.
The footage of the incident captured by fellow Flight 3411 passengers -- which included images of a bloodied Dao -- resulted in widespread indignation.
After initial missteps in which they appeared to at least partially blame Dao, the carrier and its CEO Oscar Munoz apologized repeatedly and launched the internal review to find out what went wrong.
"Our policies got in the way of our values and procedures interfered with doing what's right," Munoz said in a statement announcing the results of the review.
"This is a turning point for all of us at United and it signals a culture shift toward becoming a better, more customer-focused airline," he said.
The carrier's report highlighted 10 changes, including increasing its cash enticement to $10,000, effective Friday, to get customers to voluntarily give up their seats on overbooked flights.
"There was ambiguity (on the maximum cash offer) under our previous policy, which is why we are changing it moving forward," United spokeswoman Maggie Schmerin told AFP.
The crew on Flight 3411 had only offered $1,000, the report said.
Such flights include those that are the last of the day and on smaller planes, both of which were factors on Flight 3411.
Without enough volunteers to take later flights, airlines are forced to involuntarily "bump" passengers off overbooked flights.
"It is our goal to reduce involuntarily denied boarding to as close to zero as possible," Schmerin said.
Other changes include a new customer service team to find "creative solutions" for passengers whose flights are disrupted or overbooked -- solutions such as flying to alternate airports and using ground transportation.
United was not the only airline to announce changes, as the dragging incident and its aftermath reverberated throughout the industry.
United had already changed some policies, including no longer relying on law enforcement to deal with customer service issues.
United and American ended the practice of asking passengers already seated on a plane to give up their seats.
And Delta Airlines also raised to $10,000 the amount it would pay for volunteers to get off overbooked flights.
