Airline Operations — Scheduled, Charter, Hub & Spoke, Codeshare, Air Taxis, LCC & Haul Types
Today’s aviation passenger has more choices than ever — scheduled full-service, budget no-frills, private charters, air taxis, codeshare connections. Understanding every type of air service is fundamental for aviation and travel professionals.
✈️ Scheduled vs Non-Scheduled Air Services
Scheduled Air Services
Non-Scheduled (Charter) Services
Fixed timetable, drawn up months/years ahead
Operate seasonally or on-demand
Fixed flight numbers and routes
Flexible routes and timing
Operate even at partial occupancy
Only operate when load is guaranteed
Bookable up to 1 year in advance
Whole aircraft or section sold to one operator
Higher fares (full service)
Lower fares (full load pre-sold to agent)
Example: Air India AI 0887 Delhi-Mumbai
Example: European charter to Caribbean (Nov-Apr)
🗺️ 3 Scheduled Service Models
Point-to-Point (P2P) Service
Aircraft flies directly from origin to destination — no hub connection. Advantages: minimises connections and travel time · less baggage transfers = fewer lost bags · flight delays don’t cascade to other routes. Preferred by LCCs.
Hub and Spoke Model
Single central airport (hub) acts as connection point. Spoke routes connect smaller cities to hub. Major airlines operate multiple hubs. Advantages: fewer routes needed for large network · more frequent flights per route · economies of scale at hub airports · maximises aircraft capacity. Example: Emirates using Dubai (DXB) as global hub.
Codeshare Service
Two or more airlines share the same physical flight — each publishes it under its own airline code and flight number. Only one airline actually operates the flight (the “operating carrier”). Passenger can book A→C via B under one carrier’s code. Synchronised schedules between partner airlines. Example: Air India codeshare with Lufthansa on Frankfurt routes.
🚁 Air Taxi Services
An air taxi is a commercial aircraft making short flights on demand — like a car rental service. Small aircraft, used by business executives, celebrities, and VIPs who cannot follow scheduled airline timetables.
Key Features & Advantages of Air Taxis
✓ Fly at any chosen time — complete schedule flexibility
✓ Access to private air terminals (avoid busy airports and queues)
✓ Maximum luxury, privacy, and security (ideal for celebrities)
✓ Can reach any destination — including places not served by scheduled airlines
✓ Choice of preferred aircraft type
✓ Pilot and crew services included on request
Note: More expensive than scheduled airlines — entire aircraft at hirer’s disposal. 15,000+ business jets available globally for charter. US and Europe are largest markets; growing in Middle East and Asia.

⏱️ Short, Medium & Long Haul Flights
Short Haul
Under 3 hrs
Under 3,200 km. Most Indian domestic flights. Aircraft: A320, B737. Example: Mumbai-Kolkata.
Medium Haul
3–6 hrs
Regional international routes. Aircraft: A320/321, B737-700/800. Example: Delhi-Singapore.
Long Haul
6–12 hrs
Transcontinental routes. Wide-body aircraft: B767/777, A330/340/380. Example: Delhi-London.
Wide-body aircraft used for long-haul because they have larger engines, greater fuel storage capacity, and range. Narrow-body aircraft used for short/medium haul. Large airlines operate all three categories; smaller airlines start with short/medium haul.
💰 Low Cost Carriers (LCC)
LCCs = No-Frill airlines / Budget airlines / Discount airlines. Lower fares achieved by cutting operational expenses. World’s first LCC: Pacific Southwest Airlines (USA, early 1980s). India’s first LCC: Air Deccan (launched 2003).
How LCCs Keep Fares Low — 6 Cost-Cutting Strategies
A. Aircraft Strategy: Buy second-hand or hire aircraft. Bulk orders for new aircraft to get discounts. Single aircraft type = simpler, cheaper maintenance. Minimal optional equipment = lower weight = fuel savings. No in-flight entertainment systems.
B. Point-to-Point Operations: No hub-and-spoke = lower airport charges. Use secondary/smaller airports (cheaper landing fees). Defend specific city markets.
C. Additional Revenue: Food sold on board at extra charge. Better legroom seats priced higher. Merchandise sold on board. Excess baggage charges.
D. Minimum Comforts: Basic seats, simple food. Minimum crew to reduce staff costs. Limited food = faster turnaround = more flights per aircraft per day.
E. Minimum Personnel Cost: Staff work multiple roles (check-in staff = gate agents). Lower headcount overall.
F. Single Class Seating: No premium/business class = simpler configuration = fewer crew required.

vi. No alcoholic beverages as standard inflight offering
vii. Low to average fares — strong price competition
viii. Different fares by booking time and seat availability (dynamic pricing)
ix. No agent commissions — internet/direct booking model
x. High aircraft utilisation — short turnaround between flights
xi. Fleet of just 1-2 aircraft types
xii. Aircraft carry limited extra fuel
