1. Airport Systems Planning RdN Multi-Airport Systems in Era of Low-Cost Carriers  Dr. Richard de Neufville Professor of Systems Engineering and of Civil and Environmental Engineering Massachusetts Institute of Technology

2. Airport Systems Planning RdN Theme No-frills airlines are developing a “parallel network” of travel “network choice” (rather than “airport choice”) may determine traffic in multi-airport systems As low-cost carriers grow (and majors shrink) traffic may shift to second airports (e.g: from Boston to Providence)

3. Airport Systems Planning RdN What is a Multi-Airport System? the significant airports serving transport in a metropolitan region, without regard to ownership or political control  Ex: Boston, Providence, Manchester Discussion  This is reality for travellers  Contrasts with ACI focus on ownership

4. Airport Systems Planning RdN Planning Issue Many ‘mistakes’ in planning multi- airport systems  Washington/Dulles, London/Stansted, Osaka/Kansai, Montreal/Mirabel, etc. Failure to appreciate traffic concentration at primary airports … Because planners/forecasters using wrong mental model

5. Airport Systems Planning RdN What drives traffic allocation in Multi-Airport System? Airline competition has been primary S-shaped market share/frequency share Drives airlines to  Match flights => Allocate flights to major markets  Concentrate Traffic at primary airports Frequency Share Market Share

6. Airport Systems Planning RdN Right model: “Concentration” not “Catchment Areas” Concentration is standard urban phenomenon  e.g.: financial, jewelry, etc. districts Driven by what suppliers offer Customers choose which location (airport) depending on where they find what they need -- not just most convenient facility

7. Airport Systems Planning RdN “Concentration” persists -- until high level of local traffic When local originating traffic high… More flights add little at major airports Airlines place flights at second airports There appears to be a ‘threshold”… Currently ~ 12 million originations/year Note: higher as aircraft larger

8. Airport Systems Planning RdN Metropolitan areas with significant multi-airport systems

9. Airport Systems Planning RdN Metropolitan areas with significant multi-airport systems

10. Airport Systems Planning RdN Major exceptions to rule: technical or political Until recently, major exceptions to concentration rule were: Technical -- runways too short  Belfast, Belo Horizonte, Buenos Aires, Rio de Janeiro, Taipei Political -- or military...  Berlin, Dusseldorf/Bonn, Glasgow, Moscow

11. Airport Systems Planning RdN New Reality: No-frill airlines setting up “parallel network” Low-cost carriers “parallel” majors Major fare distinctions Ticket distribution separate  Internet direct to users, ‘no’ travel agents Parallel service between cities  Providence/Baltimore not Boston/Washington ‘No’ interlining of bags, tickets ‘Not’ in Reservation systems

12. Airport Systems Planning RdN New Reality: No-frills choose different airports Southwest, Westjet (Canada), Ryanair and Easyjet (UK) require:  Cheap properties, no Taj Mahals (compare San Francisco/International and Oakland; London/Gatwick and Luton)  Low congestion and delays  Flexible work force They find this at aggressive, ‘hungry’ airports -- not in major facilities

13. Airport Systems Planning RdN New Reality: US Network of Low-Cost Carrier Airports

14. Airport Systems Planning RdN New Reality: Europe Network of Low-Cost Carrier Airports

15. Airport Systems Planning RdN Multi-Airport Systems in Brazil

16. Airport Systems Planning RdN Importance of Parallel Network of close-in Brazilian airports

17. Airport Systems Planning RdN Implications for modelling future of second airports A new driver for second airports...  Low-cost carriers often‘not’ competing at big airports  Frequency competition does not drive growth pattern of secondary airports Competition between networks may be primary… … followed by catchment area model of airport choice

18. Airport Systems Planning RdN Implications for future of second airports No-frills airlines are becoming ‘major’  Southwest 4th largest airline in world (pax)  Market Cap ~ 12billion $ > any other pax airline  Ryanair Market Cap greater than British Airways Majors are shrinking (UAL, USAir, etc.) Implies that Primary airports will lose significant traffic to second airports This is already happening!!!

20. Airport Systems Planning RdN Market Share of Boston/Logan is in decline Source: Louis Berger New England Regional Aviation System Plan The 2003 Share is about 63%

21. Airport Systems Planning RdN Summary A new, parallel air transport network is emerging to compete with majors This low-cost carrier network may become a major feature of industry It implies growth and importance of low-cost second airports throughout North America, Europe -- and perhaps elsewhere
