Peta kursi Piedmont Airlines Embraer ERJ-145

American's public ER4 viewer for AA 5945 publishes the complete 50-seat, single-cabin grid: solo-side seat 1A and 2A, followed by 1-2 rows 3-18 in columns A/B/C. The viewer identifies row 12 as the Main Cabin Extra over-wing exit row, but current unavailability suppresses the product label on 12A; American's separate aircraft table explicitly publishes exactly 3 Main Cabin Extra and 47 Main Cabin seats, so 12A completes the exit-row trio and is marked seatTypeInferred. This availability-driven reconciliation makes provenance mixed and yields the house-style summary 3N/47Y while retaining one physical Main Cabin. The viewer marks rows 11-14 over the wing, 11B/11C as limited or no recline, and shows a front closet/flight-attendant station plus a rear washroom. No recline inference is made for unavailable 11A or row 18. Live availability is transactional and is intentionally not encoded as blocked or unbookable. AAG's FY2025 Form 10-K reports all 71 operating ERJ145s under Piedmont at an average 50 seats as of December 31, 2025. American controls the customer-facing American Eagle cabin, pricing and seat inventory and publishes this map; Piedmont is the operating carrier, so the cabin source belongs to the American brand and does not establish tail-specific differences. No engineering or photo source proves window alignment, so window seats remain unknown. Direct aa.com fetching was bot-blocked; the seat-viewer source is preserved as a rendered text capture.
