I did bag TFS-NCL with TOM for £60 in May and the flight was full... And the NCL-TFS I took with Ryanair was at least 80% and I paid something like £30
On another note, flew NCL-SXF today, A320, G-EZOK. 135 pax... When I asked "how many passengers on board today" the FA's initial response was "not many today" and he said that the Berlin flights had been selling/filling well, especially at the weekend. Rather disappointing to see that all 6 extra legroom seats in row 1, and 5 of the overwing extra legroom seats were empty... And mine was "free" as I'm an easyjet plus card holder
Nevertheless, for all it was an A320 today for operational reasons, 135 isn't all that bad, especially on the A319 which is scheduled
