the billions of debt are from emb 170 and 145 financing. most of the 145s and all of the 170/5 fleet are owned. they are financed through purchase financing and the debt is secured by the airplanes as collaterals. froentier doesnt have this, therefore no purchase fianancing.

most likely indigo will use the same method as spirit and will utilise operating lease financing, instead of purchase lease financing.

in the case of rah aircraft, they can always go abck to the banks and reduce the amount of debt and align them with current values of aircraft. the same way they did with 145s last year.
