Eurostar will restart direct services from London to Amsterdam and Disneyland Paris in the coming weeks.
The cross-Channel train operator announced it will resume its Anglo-Dutch route from July 9 and its services to Disneyland Paris from August 2.
Although direct services will run to the Netherlands, passengers travelling in the reverse direction will need to change trains in Brussels, where passport checks and security screening will be carried out.
The routes have been closed since March due to the drop in demand caused by the coronavirus pandemic.
Eurostar is offering more flexibility on all its fares, enabling passengers who book throughout the rest of the year to alter their travel plans up to 14 days before departure without a fee.
The firm said all travellers must wear a face mask as part of additional hygiene measures.
Passengers will be seated "at a safe distance apart" and trains will be "deep-cleaned" before every journey.
Passengers travelling from London will be able to check in and board the Eurostar without having their passport checked thanks to new facial verification software from next year.
Travellers who opt in will have to upload a selfie and a picture of their passport to the Eurostar's app as part of a contactless boarding system.
The technology works by cameras scanning passengers as they walk through a 'biometric corridor' at St Pancras station.
