I got the pricing from delta.com, agent will cost more. Maybe someone here can come up with something more crazy, I did not spend much time to maximize this trip. Just make sure you fly on a day when the direct DUB-ATL flight is operating, else you will have a hard time to get this price (T-class is not all that common for transatlantic travel). Someone else also suggested CO, but I could not find any useful availability. I'd wait some days if someone can find a more 'creative' routing.
Come on guys, is this really the max one can find for DUB-LAX on any Skyteam carrier?
