There are big changes for travelers that use Logan Express in Boston, Massport said Wednesday.

The service is moving its pickup and drop-off sites from Copley Square to just outside the MBTA’s Back Bay station. The change will go into effect May 1.

“As of May 1, passengers who take the Back Bay LEX will get ahead of the security line when they arrive at Logan. The fee will also drop from $7.50 to $3 for a ride to the airport, and free from Logan to Back Bay,” Massport said.

Back Bay Logan Express buses are scheduled every 20 minutes daily. The starting point for the bus route will remain at the Hynes Convention Center on Boylston Street with a stop at the Back Bay T Station on Dartmouth Street. Currently, Logan-bound passengers are picked up outside the Copley T Station and passengers from the airport are dropped off on St. James Avenue.

Service from the Hynes runs from 5 a.m. until 9 p.m. Trips from Logan start at 6 a.m. and ends at 10 p.m. every day.

Also starting in May, Massport is increasing its Braintree Logan Express service with trips to Logan scheduled every 20 minutes. Additional parking at both Braintree and Framingham locations are also in the works.

The move comes as Massport is encouraging more passengers heading to Logan Airport to use public transportation over ridesharing services such as Uber and Lyft.

The agency unveiled a plan earlier this year to move the ride-sharing services into a centralized area in the Central Parking Garage. The plan would also increase fees paid to pick-up and drop-off passengers at the airport.
