BOSTON (AP) _State transportation officials are gearing up for one of the year's busiest travel periods.

Massport says it expects nearly 1 million people to fly in or out of Logan International Airport during the days leading up to and immediately following Thanksgiving.

Travelers are advised to arrive early for their flights, take public transportation to the airport if possible and _ for those airlines that allow it _ check in online.

The MBTA will offer additional Silver Line service to the airport through Wednesday, and again from Saturday until Monday Nov. 28.

The state highway division plans to suspend demolition work at toll plazas on the Massachusetts Turnpike during the Thanksgiving holiday period.

Officials say the ongoing project to remove tollbooths and construct new traffic patterns is ahead of schedule.
