Hi! I just flew Delta Airlines MXP Terminaland had a seamless experience. Check-in at Terminal 1 was fast, and the Delta personnel were friendly and courteous. Security passedquickly, and clear signage made it easy to navigate. The lounge wasn't enormous, but spacious and well-provisioned. Boarding was well-managed and on schedule, and the gate personnel were courteous. All in all, Delta's operation at Malpensa feels smooth and trustworthy. Would recommend for transatlantic flights!
