Equity
The problem here is Equity. Anyone operating in and out of Oliver Catastrophy International will know that Equity have to be responsible for more delays to airlines than weather, check in and technical issues combined. They have a monopoly on service provision at the airport, and the airlines are powerless to do anything about it.
Having said that, its strange that the rear hold wasn't checked as this is normally the primary hold on the diesels for loading baggage and you would expect the ramp agent to check it, especially if he wasn't familier with the aircrafts cargo hold arrangements.
Teething problems will always occur with a new airline and you will probably find that the ground staff are still inexperienced.
