Financially u can call KFA and air india similar but not on a whole basis. Remember, in India things work differently if the owner is a flamboyant businessman. Air India is after all a Govt entity and private airlines are partly to blame for Air india`s current situation. It has been put to such situation to help the private players.
Coming back to KFA, Its still alive just beacuse of VJM`s reach in delhi and his networks. These `humanitarian` grounds are nothing but a backdoor channel to release funds. Yes, they cant do this for much long but this is happening for more than a year now and u never know what will happen in future.
