I was unsure about how to spend my SkyMiles when I visited the Delta Airlines Singapore Office. The staff was very understanding and gave me a thorough explanation of all my alternatives. In the end, I upgraded to Comfort+ and received excellent mileage value. I was surprised by how intimate the entire event seemed. The wait was brief, everyone was pleasant, and I left feeling much more assured about my journey. A huge thank you for their assistance!
