Air Nigeria has the IATA / IOSA approvals that Arik may never get (now almost 4 years as an airline).
Arik is a management DISASTER. The singular thing that this father / son team is good at is spending other people's money on shiny new airplanes.
Would this combined, government run entity, be better than what is currently available? Probably not, but as long as there's oil to back up the Nigerian government, there will be money to subsidize a national airline... until it is completely mismanaged into insolvency.
Sorry that my synopsis doesn't have a happy ending.
