I think the disadvantages of a Jet2 NYC service are quite obvious. Sure a 2 x weekly service over the weekend will attract those eager to sample a break in NYC, but how long will the route be sustained with no chance of onward connections and very little appeal to business passengers, requiring maximum flexibility. Potentially it could put NCL gaining a US scheduled carrier on the route back by quite a few years.
Realistically speaking I would like to see, as do many other enthusiasts, passengers, airport workers and local businesses a real scheduled service started, with onward connections available therefore opening up a whole new route network for NCL. EK have started off a small trend IMHO, the route showing there is huge potential for connections westbound, now its time for northern passengers to be offered those opportunities eastbound (Hawaii!!!!).
NCL1 on the subject of delays, where did you get the information from on Jet2 being so low in the punctuality stakes at NCL? Virtually every over other airline (TOM, XLA, FJE, EZY) have had delays - is there a table to show who is where? On the plus side some airlines who started off badly seem to be improving. It would be nice if NCL could get 'most ontime UK airport' again.
