"Dutch researchers Christiaan Behrens and Eric Pels analyze the passenger market between London and Paris from 2003 through 2009. The primary competitors in this corridor are conventional air carriers like Air France and British Airways, low-cost carriers like easyJet, and the Eurostar high-speed rail service. Over the course of the study — which looked at roughly 9,500 business and 18,000 leisure trips — the Eurostar has been far and away the dominant travel choice."
