I just flew through Delta Airlines SJO Terminal and was really happy with my experience. The check-in process was quick and easy, due to the helpful staff. The station itself was clean and easy to navigate, with plenty of comfy seats. While I waited for my flight, I took advantage of the free Wi-Fi. Security checks were swift, and boarding went smoothly. My flight arrived on schedule, and the in-flight service was superb. I highly recommend Delta at SJO to anyone traveling!
