Yeah they do, seasonal flight to Newark if wikipedia is to be believed. I was thinking that SAS/UA/SN could build some star alliance presence at NCL, then possibly lure in LH, which should hopefully create a small cycle of growth, it would be quite limited as to which airlines could feasibly operate from NCL. I can't really see SIA, SAA or ANA rushing to operate, but I think Turkish is more a case of when not if and TAP/Swiss could consider us based on whatever the next few years holds for us in terms of sustainable growth.
In some ways I feel Swiss to ZRH has more chance than LH to FRA
