I mean two things can be true at once - the budget carrier business can be a complete fugaze that never worked without artificially suppressed interest rates and was at this point, pretty much a long con job for a bailout...
and, the reason Spirit went under NOW is because of fuel costs associated with Trump's unhinged criminal war against Iran.
Like both of those things ARE objectively true. Trump doesn't get to say he didn't break it but also that whole industry is underwater and flailing.
