Heard a whisper than UA are considering a daily ORD service in 2015. Not sure its reliable however its not the first rumour about such a route. UA are due to make a routes announcement shortly and what I can gather it will be long haul but not sure if its to Europe or Asia. Heuston would be a better addition, not sure DUB needs a fourth daily service to ORD. Their current 3 daily flights are completely sold out everyday.
