The Grand Alliance and the New World Alliance will combine two all-water services from Asia to the U.S. East Coast as part of their combined capacity cutbacks of about 4,000 20-foot containers during the slack winter season, the groups announced on Thursday.
The temporary reductions, which are designed to cut capacity and sustain recent rate increases during a period of lower seasonal demand, will take effect from Dec. 1 and last for around 18 weeks.
