National Airlines isn't a "low cost carrier"... they are far from it.
They presently fly an all Boeing 757-200 fleet, I think 8 are new aircraft (deferred BA order they picked up) and the other 9 aircraft are from European and South American operators (one even flew for AeroPeru, Turkmenistanien, AirTransat, and the saudi gvt.. N517NA). The newer planes have inflight video, but I don't know if they are all operating yet.
The airline was just ranked #2 best airline by Conde Naste... First Class gives you a 40" seat pitch, coach is 33" up to row 25 I think, then the last part of the plane is the regular 32" seat pitch.
The fares are decent and they have a large growth pattern... getting 20 new planes over the next 3 years, of which 8 will be replacing the used aircraft.
