I would recommend avoiding Delta if at all possible. We had booked to fly from Atlanta to Dublin but ended up having our flight delayed 2+ hours. During the delay, the Delta desk agents would not answer any questions about the cause of the delay or how long the delay would be. The staff overall seemed to not know what was going on and even later stated that they "needed to go see what was going on" before they would be able to provide a departure time. Overall, the impression is of a poorly run airline, with staff that were unable or unwilling to answer any questions.
