I don't think OJA has been a problem. I think that bird has saved the day on the final farewell tour since late last year.
They need extra aircraft for what a friend calls 'ORG SLACK'. Hilarious as the 744 fleet is known as International Rescue. OJQ, OJR etc are a quicker fix than waiting for orders that are not even activated.
How did it get to this in the first place?
