Flixbus, Oui Bus, Eurolines and Alsa long-distance intercity coaches are by far the cheapest way to travel between London and Paris. Deals as cheap as €15 are common.
Long-distance intercity buses continue to compete with Eurostar trains and airlines when traveling between London and Paris. Although coaches are much slower than the high-speed trains, ticket prices are also much cheaper – often a tenth of the price of a Eurostar train ticket. Several coach companies offer daily services from London to Paris including big names such as Flixbus (Megabus), Ouibus (Idbus), Alsa, and Eurolines (National Express). It may be near impossible to land the oft advertised £1 specials but it is fairly easy to book one-way bus journeys from London to Paris for under €15 with two weeks notice while travelers with flexible departure dates may find deals much cheaper too.
Travel to London or from the UK to Europe often requires much longer check-in times, even for buses, than are customary for other European journeys. For Eurostar trains, the minimum check-in time is usually 30 minutes and for buses 15 to 20 minutes but double-check the notice on issued tickets.
