United Airlines hopes more cash, better training and fewer oversold flights will help the airline avoid a repeat of the controversy and public relations disaster that erupted after a passenger was dragged off one of its flights earlier this month.

While CEO Oscar Munoz continues to apologize for how the airline had Dr. David Dao removed from his flight, he is also wrestling with how to change United's culture when it comes to customer relations. As a result, United is instituting 10 policy changes when it comes to overbooking flights, bumping passengers and improving customer service.

Among the new policies that have already gone into effect or will this week:

• United will offer up to $10,000 to customers who volunteer to give up their seat on an overbooked flight. In the incident involving Dao, he and other passengers were offered $800.

• Passengers who are on board and in their seat cannot be removed from a flight unless there is a safety or security issue.
