Eurostar, which operates direct service from the U.K. to the Netherlands, will begin offering direct return service starting this spring.
The service from Amsterdam and Rotterdam to London has required a stop in Brussels for passport control and security checks since its inauguration in 2018.
The Amsterdam-London route will be direct starting April 30 and the Rotterdam-London route starting May 18.
The London-Netherlands routes will continue to operate with direct service.
Eliminating the stop in Brussels will trim an hour from the return trip, down to about four hours.
There are currently three daily services from the U.K. to the Netherlands, and return service will start with two a day, set to increase to three and eventually four per day.
Tickets, which begin at $46, went on sale Feb. 11.
