What is the possibility of getting a food allergy medical waiver from the USAF?

Military service can place members in remote locations with limited food and healthcare options. For this reason, a history of systemic allergic reaction to food or food additives is a disqualifying medical condition for individuals seeking to join the military. Sensitization – that is, elevated food-specific IgE, but no clinical history of reaction symptoms when consuming the food – is not a disqualifying condition. The different service branches use different terms to define disqualifying food allergies. The U.S. Army definition is broader, referring to a “reliable history of a moderate to severe reaction to common foods, spices, or food additives,” whereas the Air Force, Navy and Marine Corps definitions make specific references to a history of anaphylaxis.

An individual excluded from the Armed Services on the basis of food allergy history can request a waiver, which may be granted depending on the results of an appointment with an allergist. A waiver is unlikely if the allergist recommends that the prospective recruit carry an epinephrine auto-injector or if either the allergist or the recruit is reluctant to complete an oral food challenge.

depends on the severity of the allergy. I've known a couple of people who served with seafood allergies.
