Prosecutors asked that a second DUI charge and a speeding charge be dismissed.
Municipal Court Judge Joseph Olcavage ordered Parker to spend 24 hours in jail on March 15. Olcavage also fined Parker $1,646.25 and ordered him to be screened by a doctor to determine if he has a problem with alcohol addiction.
Parker was pulled over Jan. 31 after leaving a party at the FBR Open golf tournament in Scottsdale.
US Airways acknowledged the sentence in a statement to employees Tuesday: "Doug knows he made a serious mistake and has apologized for his actions. He plans to adhere to all of the court-directed repercussions and restitutions that come about from this charge."
The message also said Parker's court date was moved up one day to accommodate his attorney’s schedule, and that the CEO made the guilty plea against his lawyer's advice.
Police spotted him driving 20 mph over the posted 45 mph speed limit in his black BMW.
According to a police report, officers noticed that Parker had bloodshot and watery eyes, slurred speech and alcohol on his breath. The CEO refused to take a breathalyzer test.

His blood-alcohol level was found to be 0.096. The legal limit in Arizona is 0.08.
Police called a taxi for him and had his car towed.
