Travelers face limited choices between mainline and regional aircraft

Smaller airports often lack the infrastructure needed for larger planes. Cities like Pensacola and Wichita rely heavily on regional flights for connectivity to major hubs like Atlanta or Chicago.

Major airlines use affiliate carriers such as American Eagle or Delta Connection for regional routes that wouldn't be profitable with larger aircraft. Wingspan.mhirj.com notes that “the 50-seater market is just too big” for airlines like Delta or United to abandon because of its importance in feeding into larger networks.

Pilot shortages also impact route availability; according to thrustflight.com, the U.S. market alone faces a shortage of approximately 30,000 pilots. This shortage leads many pilots who start at regional airlines to move quickly onto mainline carriers for better pay opportunities.

Passenger experiences on regional jets vary widely: some appreciate faster boarding times while others miss first-class cabins or entertainment options found on larger planes. Newer models like the Embraer E2 series aim to improve passenger experience with better seating and fuel efficiency.

Despite a preference among travelers for mainline over regional aircraft due mainly to comfort factors—such as more space—many do not have a choice when traveling from smaller cities where only regional service is available.
