Alaska lounges:
The Alaska lounge in SeaTac airport is located in Terminal D. It is two stories and is always pretty packed and rightfully so. It is a 4 stars lounge in comparison to United or Usairways lounges.
The pros about this lounge are:
Lots of coffee to keep you going and a selection of syrups (regular and sugar free) and two levels of seating.
They do have showers, private conference rooms that fits an entire family of 6 comfortably to private small rooms to allow for those business conference calls. There is also a bar on the second floor with decent selections and daily feature selections see below.
Cons: the main room is always crowded, see pictures below.
The food selections are very limited in comparison to a centurion lounge but definitely better than a United lounge or a Usairways lounge. Breakfast: there are hard boiled eggs, pancakes, toast and bagels. Lunch: A small salad buffet available on their second floor. Available all the time are: cheese, crackers, mixed snacks, cereals and fruits (bananas, apples, oranges).
