Connection and Operational Patterns
Las Vegas is one of the largest O&D markets in the US, meaning nearly all ORD-LAS passengers are point-to-point rather than connecting. Convention calendars (CES in January, NAB in April, SEMA in November) drive load factor spikes that push fares well above baseline. The route is effectively demand-inelastic during major convention weeks. ORD is the primary origin for Midwest passengers traveling to Las Vegas, with Chicago having one of the highest per-capita LAS travel rates of any US metro. Harry Reid's single integrated road system can cause rideshare pickup congestion after large convention departures; Terminal 3 departure lanes back up during peak evening check-in windows.
