I donīt know if its is a really extreme good deal, but if you floogle (
) for MAD-MNL OW in business for 1190 eur (not shown on ITA tough). Maybe an alternative to get the OW from MNL back to NCL also with Oman Air.
Cheaper alternatives for positioning to MNL are:
IST-MNL (C) 595 eur Kuwait airlines
IST-MNL (I) 620 eur Saudian airlines
FCO-MNL (C) 940 eur Kuwait airlines
