Note: this lounge has reopened.
The Centurion Lounge located in Terminal B (near B3) at Seattle-Tacoma International (SEA) will be closing down "permanently" this weekend on January 29th at 7 pm. But don't fear, American Express will be opening their new lounge in the airports Central Terminal in the "coming weeks" according to their website!
Details of the new Central Terminal lounge are not yet known, but I expect this to be another expansion like we saw at SFO recently. I have reached out to American Express in hopes of learning more.
Rumors are floating around that the new lounge will open on February 15th, but we will know more once American Express announces more.
I will update this posting with any updates, but you can also keep tabs on information directly on the Centurion Lounge SFO page.
Some people will be annoyed with the lounge closure, but this likely will be fantastic news for those traveling to or from Seattle (SEA) in the near future. I really expect this new lounge to be larger and likely nicer. In my recent post about guest policy changes, I was a little harsh on American Express for their lounge policies, but I expect these changes of larger lounges and fewer people will make for a much better experience.
