More Eurostar trains are being added in response to growing demand following the removal of quarantine for fully vaccinated travellers from France to the UK and the easing of restrictions for travel to Belgium and the Netherlands.
The high-speed Channel Tunnel passenger service has seen bookings double in August over July and is adding 39 trains for travel between the UK and the continent this month alone.
The busiest days for travel are on the bank holiday between August 27 and 30, with Paris the most popular destination from the UK.
The high-speed rail operator is seeing a gradual return of weekend breaks since the easing of government travel restrictions earlier this month, with a 105% rise in August and September weekend trips between London and Paris compared to the same period last year.
More than 80% of bookings are attributed to leisure travel or visiting friends and family.
An updated timetable from September 6 until November 1 will see eight daily returns, with five in each direction on the London to Paris route and three in each direction between London and Brussels, with one each way extended to Rotterdam and Amsterdam.
The expanded timetable offers improved flexibility with one-way fares starting at £39.
Eurostar has introduced new measures to keep passengers safe, with trains deep cleaned before every journey, and cleaning teams on board to regularly disinfect high contact areas.
All travellers must wear a mask on board and in stations. This continues to apply after check-in at London St Pancras.
