Sơ đồ chỗ ngồi PSA Airlines Bombardier CRJ700

American's public CR7 seat viewer for AA 5180 publishes a 65-seat grid: 9 First seats in 1-2 rows 1-3 and 56 Main Cabin seats in 2-2 rows 8-21. The viewer tags Main Cabin Extra at 8A/8C, all of row 9 and all of exit row 16; American's separate aircraft table explicitly publishes 12 Main Cabin Extra seats, so unavailable 8D/8F complete the row and are marked seatTypeInferred. That yields 12 Main Cabin Extra and 44 standard Main Cabin seats, not the tentative 16/40 split. The viewer tags Preferred seats in rows 10-13; unavailable 10D is treated as part of that published row pattern and noted as inferred. This small availability-driven reconciliation makes provenance mixed. The viewer marks rows 13-17 over the wing, row 16 as an emergency-exit row, and a rear washroom after row 21. Live availability is transactional and is intentionally not encoded as blocked or unbookable. Main Cabin Extra is non-contiguous and therefore modeled as a zone/seat-type override inside the physical Main Cabin. The CRJ700 is active, not retired: AAG's FY2025 Form 10-K reports 60 PSA CRJ700s operating at December 31, 2025, alongside 62 at SkyWest, all averaging 65 seats. American controls the customer-facing American Eagle cabin and publishes the map; the AA map does not distinguish PSA from SkyWest, which use the same published 65-seat American-branded specification. No engineering/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.
