You can see how well and similar Wizz Air is to NK; 28 AC run by the same Magicians (Indigo Partners), etc, etc....

Wizz Air - Wikipedia, the free encyclopedia

The interesting read is history and finiacial performance

Maybee Indigo can not afford to lose anymore of their investors money; for they are losing face with their ULCC business model and possible IPO'ness of them if NK goes on strike... Who knows?? Poker anyone?
