RA - you yourself couldn't see this coming
This is simply press speculation from a newspaper that really ought to know better (it's that time of year). Swiss billionaires aren't in the habit of throwing good money after bad - that's why they remain Swiss billionaires that have increased their wealth over recent years, despite the "recession".
In reality, they are playing a long game and will back loans to companies in their portfolio that have served them well and will do so again in the future.
An airline's profit is but one element in the big picture. The shareholders buy and then lease aircraft that they own to the Company and are thus having their aircraft bought from the lease costs. Once these aircraft are paid for (after say 10 years) they make a substantial profit for the shareholder (not the company) for another 10 or more years, analogous to buying a buy-to-let house and having the tenants buy it for you in 10 years via their rent and therefter you enjoy another 10 years with no mortgage payments. Unfortunately aircraft tend to last not much longer than 20 or so years, unlike houses.
The point is that Monarch does not need to make money to be of value to the shareholders - why do you think it has NEVER made a substantial profit of more than £10m, despite a £700+m turnover in recent years, in over 40 years of trading?
