In relation to the 738s based at NCL, I believe that the two currently are G-GDFC, and G-GDFZ.
So that leaves 5 cuurently at NCL:
G-CELX - 737-377(QC)
G-GDFE - 737-3Q8(QC)
G-GDFH - 737-3Y5(WL) - WL's Recently Fitted
G-GDFC - 737-8K2(WL)
G-GDFZ - 737-86Q(WL)
- Having been on several Jet2 aircraft myself, (all 3 types in fact [737-300QC, 737-800, and 757-200]) I definitely agree that the cabin interior is immaculate, and someone who doesn't know anything about aircraft would think that it was bought yesterday. Jet2 and Jet2holidays are doing really well in this somewhat cut-throat market - so what if they have a different buying policy to everyone else!
