|Don't forget financial protection on your next trip.|
You can take out insurance SAFI (Scheduled Airline Financial Insurance) which is in-expensive or may be included in your travel insurance policy cover.
In reality the likes of EasyJet, Ryanair and others who are large publicly quoted companies won't go bust, but smaller companies some based overseas are always at risk. in recent history a British No Frills company nearly went bust and had the CAA intervening to ensure that solutions were put in place (EG extra working capital from new investors)
In the UK Tour Operators have to have ATOL licenses which means your travel arrangements are covered by the CAA and any repayments ultimately come from the Air Travel Trust Fund which is underwritten by the British Government.
