Do not worry about expungement. Let the license suspension terminate in 6 months. An infraction is the same thing as a traffic ticket. It does not go on your criminal record. You probably don't need a lawyer for this. But I you want more specific answers or someone to look at th paperwork you have and possibly give a more certain answer, contact an attorney that has free consultations.
The terminology your using for the DUI and how they were resolved may be critical in getting into the Air Force. I'd go back to the attorney who represented you for this and with his knowledge of what exactly the plea bargain was he should be able to give you a straight and simple answer. Otherwise you need to get a copy of the court order from the day you were in court and entered your guilty plea and have a competent criminal defense attorney take a look at it and presumably get some correct answers and accurate information.
As an USAF JAG reserve officer I can tell you a few things. First the Air Force is going to be decreased to the smallest size in it’s history. The Air Force is making tremendous cuts in the force and is by far the most selective of all the military branches. Even if this is an infraction you should get it expunged via a 1203.4a, yes you can expunge infractions. Also be careful about what questions you are asked. If you are asked about more than just misdemeanors and felonies be honest on the application. You do not want to not get selected due to a lie or be caught down the road and be discharged from the USAF for fraudulent enlistment.

The "lawyer" who told you to see if you can get a misdemeanor instead of an infraction should resign as an attorney, immediately.
Infractions can be expunged, but for military purposes it likely will not make much of a difference as an infraction is not a crime and thus you were never placed on probation.

Up until a few years ago, infractions could not be expunged. However, recent legislation has changed that and now infractions can be expunged. Whom ever the attorney was that advised you to convert the infraction to a misdemeanor was simply not current on the law. That is always unfortunate, but now you know better.
