Delta Airlines uses Terminal A at Boston Logan International Airport. It’s a clean, modern space with two gate areas—one in the main terminal and another in a satellite section connected by an underground walkway. After checking in, you’ll pass through TSA security and head to your gate. Terminal A has plenty of food spots like Dunkin’ and Legal Sea Foods, along with shops for travel essentials. Free Wi-Fi and charging outlets are available throughout. If you have access, the Delta Sky Club near Gate A7 is a great place to relax before your flight.
