The source material submitted is not an aviation news article but rather a brief Reddit forum post from r/flying in which a new Endeavor Air (EDV) conditional job offer (CJO) recipient asks peers about base seniority at Raleigh-Durham International Airport (RDU). The post contains no reported facts, data, or cited sources — only questions. No research context was available to supplement the submission. As a result, a factual analytical summary of the kind appropriate for professional pilots cannot be responsibly produced from this material, as doing so would require fabricating seniority statistics, upgrade timelines, and base staffing figures that are not present in the source.
What can be stated from general industry knowledge is that Endeavor Air, a wholly owned Delta Connection subsidiary operating CRJ-200, CRJ-700, and CRJ-900 fleets, maintains bases at several hubs including JFK, MSP, DTW, ATL, CVG, and RDU. Seniority at any given base is a function of fleet assignment, attrition rates, class sizes, and system-wide bidding outcomes — all of which change with each bid cycle. RDU has historically been considered a smaller, more junior-accessible base compared to high-volume hubs like JFK, but specific seniority standings require consulting current domicile lists published through the airline's crew management or union resources, not internet forums.
For pilots navigating new hire decisions at regional carriers, base assignment at indoctrination class is typically subject to operational need rather than personal preference, and initial base guarantees — where offered — vary by contract and class. Upgrade timelines at regionals remain highly variable and tied to system seniority, not domicile seniority alone. Pilots seeking accurate, current data on EDV base seniority should consult the Endeavor Air pilots' contract, published seniority lists, or the Air Line Pilots Association (ALPA) representation structure at EDV directly.
