For an airline that is medium sized or larger (ie 50 aircraft each with 150 seats), does anyone have an idea of how much of the company's costs would be variable (fuel, air nav charges, per-pax airport charges, etc) versus fixed costs (salaries, debt repayment for new aircrafy, rental on office space, etc) ?
Furthermore, how much of these fixed costs can be cut (eg staff redundancies) without the risk of being sued heavily in court (eg by aircraft lessors) ?
I realise that every airline is different and commercial confidentiality mean exact figure are private - but there must be some sort of ballpark ranges for this
