Cómo se construyó este mapa

Cabin seat counts (60 Polaris / 24 Premium Plus / 62 Economy Plus / 204 Economy = 350) per Wikipedia's United fleet table. Class layouts (Polaris 1-2-1, Economy Plus/Economy 3-4-3) plus Polaris bed size and Economy Plus 34-inch / Economy 31-inch pitch are from United's 2017 newsroom release; Premium Plus (added ~2018-2019, converting some of the original 102 Economy Plus seats) is 2-4-2. IMPORTANT - the ROW GRID is DERIVED, not a placard scan: united.com is bot-blocked and competitor seat-map sites are prohibited sources. Row numbers, exit-row placement, furniture positions, over-wing range, and the rear-taper / galley-reduced partial rows (23, 29, 49, 50) were constructed to reproduce United's published per-cabin totals and abreast layouts; they may differ from the actual aircraft placards. Polaris rows 1-15; Premium Plus rows 20-22; Economy Plus rows 23-29 (row 29 reduced to the center pair by side galleys to reach 62); Economy rows 30-50 (rows 49-50 taper to reach 204). Seat widths, recline values, Premium Plus pitch/width and non-Polaris screen sizes are not published by United and are flagged unsourced.
