I’ve been wondering the same. Part of the issue of giving these shaky airlines bad press is that that bad press is to some extent a factor in doing these airlines in by perpetuating the negative sentiments and driving consumers to take their business elsewhere.
Positive factors for Norwegian (in the short term) :
Money they’re getting from aircraft (and engine?) manufacturers to compensate them for grounded jets due to design flaws (IIRC this is applicable to 737Max and 787).
Strong summer yields
Revenue from short term leasing, as a result of the recent equipment shortages
Acquisition talks with IAG, though realistically I don’t think this is going anywhere anytime soon
Negative factors for Norwegian:
Rising fuel costs
Increase in CC holdbacks due to issuers concerned about their solvency (this factor alone has done in many an airline)
