Rail operator Eurostar is introducing a new class of service, Standard Premier, to replace its Leisure Select carriages.
The "mid-class" offering will sit between the existing Standard and Business Premier in terms of service.
It is aimed at the "cost-conscious business traveller, but also leisure travellers who want that little bit extra space and service" said Eurostar.
Tickets for the new class will go on sale from May 5, for travel from September 1.
Nick Mercer, Eurostar's commercial director, said: "Following extensive research and feedback from our corporate clients and business travel agents, it became very clear that there was a strong appetite for a mid-range product pitched between our fully-flexible Business Premier and Standard classes."
Travellers will be offered a "light meal" on board and a selection of magazines.
Eurostar will offer semi-flexible fares on Standard Premier bookings, which means the ticket is refundable with a deduction of 15% of the full value of the ticket, or of the outstanding ticket value if one of the legs has already been travelled.
