I told you the sources - CAA passenger statistics. Look it up. My comments are based on facts which can easily be verified, yours are based on your friends behaviour. Not exactly scientific.
And what can this statistics tell us when quite a big part of the airlines fly either only to EDI
and quite a few destinations are only offered on one airport.
|Quoting IADCA (Reply 102):|
You're fighting anecdotes with anecdotes.
There's a whole branch of economics that considers problems like this, called industrial organizational economics. One thing they do is apply a bunch of tests, such as Elzinga-Hogarty and many others, to determine separateness of geographic markets. One place these analyses get applied is in antitrust and competition analyses by authorities like the EC and U.S DOJ. If you can show me an example of either the EC or an airline (probably the two most available sources relevant to this debate) analyzing GLA and EDI as a single market for airline service, then I'll side with you. Absent that, I'm inclined to believe that for the market-relevant of travelers (both inbound and outbound), these are separate markets.
Than bring the analysis.
One airline analysing it as a single market is exactly Icelandair, with no plans to serve both.
Wizz Air, West jet, Virgin Atlantic for TATL, Thomas Cook, Onur Air, Niki, Icelandair, Emirates, Air Malta and AirTransat fly only from or into GLA
Turkish Airlines, Vueling, United, SAS, Qatar, Norwegian Air Shuttle, Iberia express, Freebird, Finnair, Ethiad, Edelweiss, Brussels Airlines, AUA
, Atlantic Airways, Air France and Air Canada Rouge are only at EDI
Airlines serving both airports to and from different destinations.
Lufthansa in GLA
does Munich in EDI
does Phyladelphia from GLA
If you wan to go with Air Lingus to Donegal you have to go to GLA
does Alicante, Barcelona, Faro, Ibiza, Malaga, Menorca, Nice, Palma de Mallorca, Reus, Salzburg, Venice-Marco Polo, Verona from GLA
but not from EDI
Easyjet does not fly a big part of their destinations from both. Same for Jet2 and Ryanair.
So apart from the LHR
run you have pretty much to check each time where the direct flights are from, EDI
Airports only 80 km or one hour driving apart will let people move to the airport with the airline or connection they prefer in each case. Airports further apart still influence each other.
