Update 3/18/19: This lounge has now reopened.
Update 3/7/19: We now know that this lounge will be closed starting March 11th, 2019.
American Express just reopened the Las Vegas Centurion lounge, although the Miami lounge continues to be closed for expansion. The official centurion lounge website for Seattle-Tacoma has been updated and now clearly states:
The Seattle Centurion Lounge will be temporarily closed for a short period in March as we renovate and improve the space.
Given this is for renovation and not expansion I’d expect it to be closed for a week or so, but we don’t have exact details when in March it will be closed and for how long. The Priority Pass options aren’t great either, there are two ‘The Club’s’, one in Concourse A and the other in the South Satellite.
