These Debts are very substantial and will only grow, given the under reported brewing war between Saudi and it's Allies and Iran.
That would push up oil prices and may cause routes to be cut.
Airlines come and go seems madness to begin so much debt at NCL then buy LBA with terrible debt and some vain hope of building a new taxiway and runway/ terminal extensions.
If only one of Australia's largest investment companies had access to your advice...
ps. are Saudi and Iran really involved in a "brewing war"? Seems unlikely...
