NRT may consolidate existing terminals to a single terminal
Narita International Airport Corporation, the company that operates passenger terminals at NRT, has established a working group to plan the consolidation of existing terminals. Currently, NRT has three terminals. The plan is to consolidate the current three terminals into one big terminal. By end of this year, the working group will complete the preliminary plan for the consolidation to a single terminal and the timeline of the work.
This sounds like a big construction project which can last a few years, given that NRT will continue to operate as usual. It is hard to imagine during the construction passenger experience at the terminal will be a pleasant one. One advantage is that NRT not being 24 hrs. airport. They can plan the work which will have the biggest disruption to passengers to be conducted when the terminal is closed.
