The Eurostar is great and I've taken it quite a few times. But realistically, it is way too expensive right now to seriously compete with flying for most people. It is typically 2x-3x as expensive as flying from Heathrow/Gatwick to CDG, for example. That really adds up if you are traveling with multiple people. We really need more services and more competition.
