In May 2011, services were introduced between London and Norwich, Leeds and Edinburgh, and London and Swansea and Pembroke Dock with through ferry fares to Rosslare Europort in Ireland.
Additional journeys were added to several existing routes.

From April 2012, Megabus began cross-nation services linking the UK to continental Europe, from Birmingham and London to Paris and from Leicester and London to Brussels and Amsterdam.
This was announced a month prior to the introduction of the services.
A third route, which operates entirely outside the UK, links Paris, Brussels and Amsterdam.

In 2013, Megabus started a route between Cologne, Brussels, Gent and London.

In 2014 Megabus launched a route between London, Paris, Toulouse and Barcelona.
In Germany, as megabus.com GmbH, they also launched a route between Cologne, Frankfurt, Stuttgart and Munich.

On 24 June 2015, Megabus launched first intercity bus services in Italy with 22 coaches out of a depot in Bergamo.
The five main routes are:
Turin-Venice stopping at Milan, Verona and Padua
Turin-Naples stopping at Milan, Bologna, Florence and Rome
Milan-Naples stopping at Bologna, Florence and Rome
Venice-Naples stopping at Padua, Florence and Rome
Milan-Rome west coast stopping at Genoa and Pisa

On 29 June 2016, Stagecoach Group announced that all operations in the European mainland, as well as those services linking London with Europe, had been sold to German competitor Flixbus from 1 July 2016 with Megabus serving as a contractor so no route changes were made.
This left only domestic UK operations under the control of Stagecoach.

On 1 May 2017, Megabus commenced operating five services from London, Gatwick Airport and Heathrow Airport to the West of England.
These are operated by South Gloucestershire Bus & Coach.

As of October 2017, Megabus have created a new M39 service, running from Aberystwyth to Birmingham, via Welshpool and Shrewsbury.
This service is operated by Mid Wales Travel.

In March 2018 the Advertising Standards Authority banned Megabus from using adverts promising £1 fares as few seats were available at this price.
Megabus' response was to withdraw the £1 fares altogether, leading some passengers to note that the ASA's decision has worked to the detriment of Megabus customers.

The business and assets of South Gloucestershire Bus and Coach have been bought by Stagecoach with the acquired business's owners to step down.
