Regional Airlines: How They Work, How Safe They Are

Regional airlines connect smaller cities with major hubs and help keep the whole airline network running, especially in the United States and Europe. For aspiring pilots they are often the first step into airline flying, while for passengers they are sometimes the only way to reach a nearby airport.

What is a regional airline?

A regional airline is a carrier that operates scheduled passenger flights with smaller aircraft on short‑ and medium‑haul routes, usually linking smaller communities to major hubs. These airlines typically use regional jets and turboprops rather than widebodies and focus on frequency and connectivity rather than long‑haul travel.

Regional vs. major airlines

Regional and major airlines follow the same safety rules, but differ in size, routes, and business model. The table below shows the main differences.

Characteristic	Major Airlines	Regional Airlines
Typical aircraft	Narrow‑ and wide‑body jets (e.g., A320, B737, B787)	Regional jets and turboprops (e.g., Embraer 175, CRJ‑700, ATR 72)
Seats per aircraft	120–350+ seats	30–100 seats
Typical routes	Longer, high‑demand domestic and international routes	Short‑haul routes between small cities and hub airports
Brand on the ticket	Own brand (e.g., Delta, United)	Often flies under a major brand (e.g., Delta Connection, United Express)
Role in network	Operates trunk routes and long‑haul flights	Feeds passengers into hubs and serves thin routes

Aircraft and operations

Typical regional aircraft

Most regional airlines operate jets in the 50–100 seat range and some turboprops on shorter routes. This size allows them to use shorter runways, keep costs lower on thin routes, and offer higher frequency than a mainline jet would justify.

• Regional jets: Embraer 170/175/190, Bombardier CRJ‑700/900/1000.
• Turboprops: ATR 42/72, De Havilland Canada Dash 8 series.

How regional airlines operate with majors

In North America and parts of Europe, many regional airlines operate under capacity‑purchase, codeshare, or feeder agreements. The major airline sells the ticket and controls pricing and schedule, while the regional partner operates the flight using the major’s flight number and livery.

Examples include:

• American Eagle – a network of regionals flying for American Airlines.
• Delta Connection – several regionals flying for Delta Air Lines.
• United Express – regional partners flying for United Airlines.
• SkyWest Airlines – a large independent regional operating for multiple majors.

Business models in regional aviation

Codeshare and feeder agreements

Under a codeshare, a flight operated by a regional airline appears in booking systems under the code of the major airline, which expands the major’s network without adding its own aircraft on thin routes. Feeder agreements explicitly focus on bringing passengers from small airports into hub airports, where they connect to long‑haul flights operated by the major carrier.

Why Majors Use Regional Partners

• Cost efficiency: operating small jets and turboprops is often cheaper for a specialized regional carrier than for a large mainline airline.
• Network reach: majors can serve dozens of small cities without basing their own crews and aircraft there.
• Frequency: regionals can run multiple daily flights on thin routes, improving connectivity for business and leisure travelers.

Passenger Experience and Safety

Cabin Comfort and Services

On regional jets built in the last decade, cabin layouts increasingly resemble mainline aircraft, with improved seating, Wi‑Fi on many routes, and modern interiors. The main limitation is cabin size: overhead bins and legroom can be tighter, and service is often a simple snack and beverage on short sectors.

Baggage and Boarding

Baggage limits on regional flights usually follow the major airline’s policy, but smaller cargo holds can mean more gate‑checked carry‑on bags on full flights. Passengers often board via stairs or buses at smaller airports, which can add a few minutes but does not affect safety.

Are Regional Airlines Safe?

In countries like the United States and members of the European Union, regional airlines are regulated under the same commercial rules (such as FAA Part 121 or EASA regulations) as major airlines. They must meet the same standards for pilot training, crew duty limits, maintenance, and operational procedures.

Accident statistics over the last decade show that commercial regional operations have a very low accident rate comparable to that of major carriers, thanks to improved training, modern aircraft, and stricter oversight introduced after past incidents.

Training, Maintenance, and Safety Culture

Pilot Training and Checking

Regional airline pilots must hold a commercial pilot licence.They undergo recurrent training and simulator checks several times per year, just like pilots at major airlines.

Maintenance Standards

Regional fleets follow manufacturer maintenance programs and regulatory requirements, including regular inspections, component overhauls, and strict defect reporting. Many regionals use large maintenance providers or in‑house MRO facilities audited by aviation authorities and major‑airline partners.

Career Opportunities for Pilots

Hiring Requirements

Regional airlines often serve as entry points into airline flying for new commercial pilots. Typical minimums in the US include:

• Commercial pilot licence with multi‑engine and instrument ratings.
• First‑class medical certificate.

Training Pipelines and Partnerships

Many regionals partner with flight schools and universities to create cadet or bridge programs that offer conditional job offers once hour and training requirements are met. These pipelines can shorten time to the right seat and provide mentoring, financing options, and clear progression milestones.

Pros and Cons of Working for a Regional

• Pros: faster upgrade to captain, high flight‑hour accumulation, exposure to a variety of airports, and a realistic path to a major airline through flow‑through or hiring agreements.
  
  
• Cons: starting pay and benefits may be lower than at majors, schedules can involve more short legs per day, and commuting options may be limited from some bases.
