"got lucky & line was short! Service was fast. I ordered the iced pistachio latte and it tasted great! Syrup tasted better that the Starbucks pistachio one & the coffee flavor was nice as well. Would recommend to give it a try :)"

"Got a vanilla cold brew, a bit on the bitter side, just asked them to make it a little sweeter! Chicken pesto sandwich was delicious. Great snack before the flight."

"Stopped here while we were flying out with Alaska. $9 for a cold brew nitro, $6 for a mocha. Their touch screens were half not working and the receipt paper was out. The coffee came fairly quick and hot which I appreciate because we were in a bit of a rush to get to the gate. Coffee was average but fairly strong so can't complain. With the lack of customer service, wait time and drink choices I didn't tip as much as I normally would. All in all I'd come back but I'd probably look for a different place to try next time."

"I had a good experience here. I ordered the iced lavender cold foam latte at the kiosk and it was ready in 2 minutes. The latte had good flavor and wasn’t very strong. I forgot to take a photo until I already drank half of it. Overall good coffee."

"⭐️⭐️⭐️⭐️⭐️ Costa Coffee at SeaTac International Airport is a total hidden gem for travelers! I stopped by during a layover and was immediately impressed by the welcoming staff and the cozy, clean setup. The baristas were lightning fast but still took time to make my flat white just right—rich, velvety, and piping hot. ☕✨ The pastries were fresh and surprisingly delicious for airport food—definitely grab the almond croissant if you see it! 🥐 The seating area gave me a great little pocket of calm amid the airport bustle, and the charging outlets nearby were a huge bonus. 🔌💺 Whether you’re racing to your gate or have time to spare, this Costa is absolutely worth the stop. Fuel up and fly happy! 🛫"
