I remember that consent/voluntarism being important to the lawfulness of airport searches, but I thought the big two elements of administrative search were (1) searches not being intended to collect evidence for criminal investigations and (2) officers not having discretion as to who to search.

Negatory. Consent is not relevant in the case of airports, per the 3rd and 9th circuit courts.
