What elements of the infantry to you like? Is it leadership of many? Is it the lifestyle? Aircraft maintainers tend to have larger leadership roles as I understand it. You can also cross-commission into the Army after graduation. I have a close friend who joined the skydiving team and simply loved it. He wanted to do it as a job, so he cross commissioned into the Army and became a Ranger. He is approaching 20 years right now and still loves it. Cross commissioning is not super common, but it happens at each Academy. A mentor of mine went USNA but commissioned USAF. USMMA grads choose their path and almost half of the class last year went military and they all chose their follow-on branch.
Bottom line - do what you are passionate about and put less emphasis on the commissioning source. The printed material does not highlight this option, but it is there. Those who seek it out find the info they need and there is a process. Some cross-commissioning programs may require special schooling that you do as part of your summer leadership electives, so inquire early - you don't want last minute surprises, but I would also encourage you to not really play up your desire to cross commission in the interview process. Focus on getting in, and then do your research about changing branch of service.
