Whilst the balance sheet and income statement do not look brilliant, the company has not yet run out of runway. I wouldn't panic, therefore, and maintain reservation. If you feel the concern is more than you're willing to handle, I'd consider taking insurance that protects you against cancellation of the flight due to airline failure. Standard travel insurance policies offer such coverage.
The fact SNBA is trying to secure its future with the support of shareholders - if not at their behest - is a sign there's still some (financial) commitment to the survival of the company.
