Aviation Economics

Value added chain

(Passenger & Freight transport)

Transport to airport → Travel services → ground handling (passenger/plane) → taxiing → air transport services → air traffic control

 

Aviation Economics

Aviation Markets & Actors: Markets, Carriers, Characteristics

Markets: line ops (cont. - intercont.), charter, freight transport, GA

Carriers: national flag carriers, hub carriers & alliances, LCC, specialised freight operators, specialised business aviation

Characteristics: global market (few borderlines), impacts local - regional - global, HiTech-Industry, early liberalisation & deregulatin, private acotrs - public ownership structures, high level of exposure (visibility, vulnerability)

Aviation Economics

Aviation Markets & Actors: Linienfluggesellschaften, Charter, Billigflieger

Linienfluggesellschaften: Geschäftsreisen, Wochenendflüge

Charter: Pauschalreisen

Billigflieger: Preissensibles Freizeit-/Besuchsgeschäft

Aviation Economics

Specific service concepts

Direktverkehr

Aviation Economics

Specific service concepts: LCC characteristics

No frill: reducing to the max (outsourcing to the customer)

Direct relations with short slots & quick circulations, high load factors

Standardised fleet for short haul flights

Internetmarketing & ticketing

Beneficial age structure, high productivity

Low cost airports(no hub airports!)

Aviation Economics

Die Freiheiten der Luft

1. Hoheitsgebeit eines fremden Staates ohne Landung überfliegen

2. Nichtgewerbliche Zwischelandung (Tanken, Wechsel Flugpersonal, Technical Stop) in fremden Staat (keine Aufnahme/Absetzung von Gästen, Fracht)

3. Transport von Gästen, Fracht in fremden Staat (aus Heimat)

4. Transport von Gästen, Fracht aus Vertragsstaat in Heimatstaat

5. Transport von & nach Drittstaat, wobei Start oder Ende in Heimatstaat sein muss

6. Transport von Vertragsstaat nach Drittstaat (mit Zwischenlandung in Heimatstaat)

7. Transport zwischen zwei fremden Staaten (ohne Verbindung zu Heimatstaat)

8. Transport zwischen zwei Orten innerhalb eines fremden Staates (Kabotagerecht) mit Zubringer aus Heimatstaat

9. Transport zwischen zwei Orten innerhalb eines fremden Staates (Kabotagerecht) ohne Zubringer aus Heimatstaat

Aviation Economics

Liberalisation & deregulation (Before & After)

Before: no market access (single destination), capacity reduction by bilateral agreements (50/50 rule), pooling & code sharing (bilateral allocation), tariff control, state ownership

After: new production concepts (LCC, Hub carrier): economies of scope, concentration & alliances: economies of scope & scale, globalisation & regionailsation: economies of scope & density, massive reduction of tariffs -> boost of demand, new ownershp models & financing schemes

Aviation Economics

3 pillars of growth in the airline industry

Organic growth (securing the leading positionin traffic flows)

Partner & Alliances (developing global presence)

Acquisitions (strengthening the position of hometurf)

Aviation Economics

Einflussgrössen der Planung

1. Markt & Nachfrage (Strategie/Marktanteil, Pax-Volumen, Wettbewerb, Kooperationen..)

2. Operative Parameter (Leistungsdaten, Crew, Technolgie, Abfertigung..)

3. Planungsparameter & Restriktionen (Flotte, Slots, Blockzeiten, Verkehrsrechte..)

Aviation Economics

Air transport pricing (airline tariffs & airport fees, ATC charges, taxes)

Airline tariffs: from monopoly pricing to dynamic pricing systems (yield management), dynamic pricing & best prices (early & late booking), differentiated hub & feeder prices, pass through of fuel prices

Airport fees: landing & pax charges, parking & terminal charges, environmental surcharges, slot peak charging (partly)

ATC charges: 2 part pricing (fixed baseprice & distance related charging), no differentiation according to slots

Taxes: VAT & mineral oil taxes only for national transport, Emission trading scheme in EU

Demand of Air Transport

Definintion of Customer Value

The costumer value consists of perceived benefits & extra-benefits of the customer in the process of collaboration & for the effort/service of the supplier

Demand of Air Transport

Demand measurement: Analysis & Preferences

Qualitative analysis: in-depth interviewing, case-based research, observation sutdies...

Quantitative analysis: survey research (personal interviews, surveys), experimental research

Explicit preferences: stated preferences are affected by the actual condition or event (identity with home carrier, support of national airline..)

Implicit preferences: hidden preferences will be published unconsiously & represent almost real situation (comfort not to switch to other systems, insecurities about other airlines..)

Demand of Air Transport

Demand varies by:

time of day

day of week

journey purpose

importance of speed, cost, frequency

area

Demand of Air Transport

Classic four-stage modelling systems

1. Trip generation & attraction [Activity?]

2. Trip distribution (combinations of origin & destination) [Which destination?]

3. Mode choice [Which modus?]

4. Assignment (assign flows to links, connection (public transport) & routes (car) [which route/connection?]

Demand of Air Transport

Reveales & Stated Preference Data

RP Data: real world choices, attribute likely correlated, only existing alternatives, limited obersvations per respondent

SP Data: hypothetical context (experiment), attribute relations controlled, present & future options, reliable only if taken seriously, multiple observations per decision maker, design issues

=> can be combined!

Environment of Aviation

The Aviation System

Consists of

  • Social system
  • political system
  • ecological system
  • technological system
  • economic system

These sysems affect:

  • Supply system
  • demand system

Environment of Aviation

Political System: Main topics

  1. Safety
  2. Fair markets (competitions vs monopolies, basic conditions)
  3. Access of CH to world
  4. Negative effects (noise, emmisions)

Environment of Aviation

Political System: improve Safety

What can be done to create a system which is insensible toward failures & resistent against accidents (

  • why did system fail?
  • why wasn't the system able to detect the failure or to prevent it, before the failure happened?

NOT

  • which single causes or cause chains did lead to the accident?
  • what part/component/person did possibly fail?
  • who is responsible?

Environment of Aviation

Economic System: causal relationship between air service liberalization & economic growth

liberalisation/deregulation ⇒ new & better air services ⇒ traffic growth ⇒ economic growth ⇒ job growth

Environment of Aviation

Economic System: Effects

Induced effects: industry supply chain, spending of direct & indirect employees
Wertschöpfung & Beschäftigung der Unternehmen, die von den Ausgaben der im direkten & indirekten Effekt Beschäftigte profitieren

Indirect effects: industry supply chain
Wertschöpfung & Beschäftigung der Luftfahrt-Zuliefererbetriebe & der Zuliefererbetriebe der Zuliefererbetriebe.....

Direct effects: within the industry
Wertschöpfung & Beschäftigung der Luftfahrunternehmen in der Schweiz

Catalytic effects: impact on other industries
Wertschöpfung & Beschäftigung, welche durch die Ausgaben der ausländischen Passagieren in er Schweiz ausgelöst werden, sowie indirekte Wachstumseffekte, welche die Produktivität der Wirtschaft oder die Standortattraktivität erhöhen

Environment of Aviation

Ecological System

Growth air transport -> Carbon pricing

Emission trading instead of tax

  • airlines receive a specific amount of tons of CO2 emissions, which they can use per year
  • if more is needed, the can buy more form other airlines, which have CO2 emission allowances in excess

Environment of Aviation

Technological System

Efficiency of an airplance increases with increasing size

Technical development: noise reduction, integration of pax cabine / cargo in wing, fly by wire, power supply, ...

 

Environment of Aviation

Social System: positive & negative aspects

Positive: connectivity, social inercultural interaction, time savings

Negative: noise & health impact

Introduction

Definitions to learn:

  • ARP
  • ASK
  • CASK
  • RASK
  • RPL
  • SLF
  • Yield

  • ARP: Average Revenue per Passenger
  • ASK: Available Seat Kilometer
  • CASK: Cost / ASK
  • RASK: Revenue / ASK
  • RPK: Revenue Passenger Kilometer
  • SLF: Seat Load Factor = RPK / ASK
  • Yield: return

Introduction

Definitions to learn:

  • ATC
  • CRS
  • Flights
  • Leg
  • PAX

 

  • ATC: Air Traffic Control
  • CRS: Computer Reservation System
  • Flights: number of flight number departures (i.e. LX183 SIN-BKK-ZRH = 1 flight)
  • Leg: a flight from A to B / from A to A
  • PAX: Passenger

Introduction

(LCC): Ticket price = base price +

 

  1. mandatory fees (airport taxes, payment fees)
  2. optional fees (seat reservation, additional baggage)
  3. penalty fees (airport check-in)
  4. additional services (rental cars, travel insurance)

Introduction

Demand for air travel

  • income depends on economic growth
  • increased income (expectation)
  • low prices of airlines tickets

⇒ demand for air travel increases

[GDP growth & Income growth = perspective leisure & international business tourism]

Introduction

most important economies

economies of technology

  • newer planes do have lower CASKs
  • smaller planes are able to fly longer distances

economies of scale

  • bigger planes have lower CASKs
  • bigger airports are cheaper per PAX

economies of scope

  • bigger companies provide mor ODs with comparably fewer legs

economies of density (s-curve effect)

  • airlines dominating a hub show comparably higer market shares

 

Airline Pricing

Determinants of flight price fixing

  • company target on this leg
  • composition of demand
  • situation of the competition
  • interests of other airline companies
  • political air traffic targets of the authorising agency
  • market potential
  • cost of production

Airline Pricing

What is Yield?

Yield-Management?

Yield means the revenue per PAX resp. per PAX-mile
Yield depends n the average revenue per PAX respective of the seat load factor

Yield-Mngmt aims at optimising the revenue (maximise return)
- differentiation by market segment/client category
- differentiation by time of consumption
- differentiation by time of booking
Yield Mgmt can be understood as development & implementation of fares & booking classes as well as the control of the theoretic load factor along the period.
 

Revenue Management

Price discrimination

Different prices are charged to different groups of consumers for an identical service

Conditions:

  • Consumer groups with different price elasticity (or Willingness to Pay)
  • No arbitrag, lower paying customers can't resell to higher WTP customers

-> different WTP is related to purpose of trip: leisure vs business

Revenue Management

Opportunity Costs

Price discrimination creates significant opportunity costs:

  • customer with higher WTP tend to book later
  • seat capacity cannot always accomodate complete demand

If a seat is sold at low price now, the opportunity is lost to sell it at a higher price later

Revenue Mgmt takes advantage of this optimization potential by puting booking  limits on low fares, restricting the availability

Revenue Management

Consequences of demand dependency

  • High WTP customers find low fare booking classes open & book those
  • forecaster sees less high WTP demand
  • optimizer pretects less seats in higher classes
  • go to 1

Without counter-measure, automated RM system induces sprial-down to the lowest fare

Additional (manual) closure rules need to be introduced.

Revenue Management

What is real problem?

Revenue Mgmt: What is the optimal availability given prices & independent estimate?

Pricing: Which fare levels, which rules, match or not match?

The real problem: What price should I charge?

Answer (theory): Choose price such that marginal revenue equals opportunity costs (+variable costs)

Slot Coordination

Why is a Slot Manager needed?

 

A slot & capacity manager is needed, especially in Europe

  • growing imbalance between air transport needs & adequate airport & airspace infrastructure
  • lack of airport growth potential
  • operational condition limitations

Slot Coordination

Why is a Airport Level?

Level 1 → non coordinated
no constraints, no coordinator in charge, data collection voluntary

Level 2 → schedule facilitated
some constraints applicable, schedule facilitator in charge, data collection, proposed schedule adjustments by facilitator are voluntary for airlines/operators, NO slot alocation, NO historical precedence

Level 3 → coordinated
All declared constraints applicable, coordinator in charge, data collection, slot allocation by coordinator is obigatory for airlines/operators, historical precedence, coordinator shall monitor usage of slots

ZRH: restrictions like curfews or quota rules & RWY capacity for planning purposes
GVA: terminal / passenger capacity + above mentioned (ZRH)
 

 

Slot Coordination

Who owns a slot?

A slot is a user right not a possession!

Slot means the permission given by a cordinator in accordance with this regulation to use the full range of airport infrastructure necessary to operate an air service at a coordinated airport on a specific date & time for the purpose of landing or take-off as allocated by a coordinator in accordance with this regulation [European regulation EEC 95/93 amended 793/2004 Article 2A]

Slot Coordination

ATC Slot versus ATFM? &
Airport Slot versus ATFM?
 

ATC Slot versus ATFM?
As long as ATFM capacity is sufficient NO ATC slot is needed (comparable to traffic light system)

Airport Slot versus ATFM?
Airport Slot = longer term airport planning instrument for ARR & DEP to opimize & balance scarce airport system capacity & to contribute to a better balanced ATFM

Slot Coordination

Coordination Process

  • Capacity Review
  • Historical Precedence (Grandfather Rights - use it or loose it rule)
    • A series (min 5) sots allocated to an air carrier, entitles that carrier to the same series of slots in next equivalent scheduling period
  • Submission
  • Initial Coordination
    • Historics = basis (first historic submission then historic re-timings)
    • new entrants (fewer than 5 slots on specific day)
    • new requests
  • IATA Slot Convention
    • twice per year
    • open for airlines & officially appointed coordinators
    • main task: coordination/allocation of t/o & ARR slot, evaluaton alternaties, slot exchanges, bilateral evaluation projects
  • Slot Return
  • Slot Monitoring
    • CRS Monitoring (after Slot Handback deadline, twice a year)
    • performance monitoring (bi-weekly after start of season)
    • SHL monitoring (after end of season)
    • Ad-Hoc monitoring (weekly)

 

Network Management

Supply - Demand cycle

  • Supply < Demand: undercapacity
  • ⇒ good yields, everybody achieves good results
  • ⇒ gathering of market shares, excessive capacity growth
  • Supply > Demand: overcapacity
  • ⇒ price wars, yield deterioration
  • ⇒ cost & capacity Cutting
  • Supply < Demand
  • ⇒ and so on :)
