TOM do long-haul flights from EMA, but admittedly yes NCL does have more long-haul pax flights as you have EK and now UA too.
EMA's traffic is also much more seasonal in nature than NCL's, so during the summer months EMA is noticeably busier.
Despite ZB leaving EMA, 2015 will probably be very similar to 2014.
How is NCL looking?
To be honest even if it's looking only fractionally busier for 2015 then you'll probably keep 10th place. If NCL is stagnant or sees even small declines though then its possible that EMA might over take.
