What the card unlocks at SEA#

The Platinum Card (card page) carries five lounge benefits: Centurion Lounge, Delta Sky Club, Plaza Premium, Escape Lounges and Priority Pass. At Seattle-Tacoma International three of them apply, opening 6 lounges:

The former Delta Sky Club in the South Satellite is listed as permanently closed and is not counted.

My picks by terminal#

  1. Delta Sky Club (A): Concourse A near gate A1, full bar, four showers, the hub flagship.
  2. The Centurion Lounge: Concourse B on the Central Terminal mezzanine, craft cocktails, two showers, opened 2015.
  3. The Club SEA (S): South Satellite above gates S9 and S10, full bar, two showers.

Delta flyers on Concourse A should start at the Sky Club; everyone else should aim for the Centurion Lounge, which is walkable airside from the central gates. Proprietary network lounges usually beat Priority Pass rooms, but they queue at peak, and The Club SEA (S) is the strongest Priority Pass fallback for South Satellite departures.

The fine print#

The annual fee is USD 895. Guest rules differ by benefit: Centurion guests are charged unless you meet the spend threshold, Delta charges per guest and caps Platinum visits, and Priority Pass guests follow the card's allowance. A same-day boarding pass is checked, the Delta Sky Club requires a same-day Delta flight, and the busiest lounges cap entry. The Seattle-Tacoma International page lists all 14 lounges in the directory, including the Alaska Lounges this card does not open.

How we score#

Ratings are editorial on a 1 to 5 scale. Read our methodology and the 5 best lounges at SEA.

Putting this into practice#

The names I'd check against the actual boarding pass include The Centurion Lounge, Delta Sky Club (A). I would start with the terminal and the time available after security. That turns a directory into a realistic shortlist. A lounge can be excellent and still be a poor choice for this departure if reaching it uses most of the waiting time. The location notes above should do as much work as the overall score.

The access check comes next. I'd identify the exact card, membership, status or ticket being used and read the conditions for that route into the lounge. A lounge appearing on a card's map is a starting point for that check. It is not a reason to assume every fare, guest or departure will qualify in the same way.

I would decide what I want from the stop before comparing amenities. For a meal, the food available during the actual visit matters. For work, I'd look for a suitable seat and power. For a short connection, simply finding a comfortable place near the gate may be the better result. There is little value in an amenity I cannot use.
