With respect, it is not about full loads.
You are absolutely correct, however the knock-on effect of cancelling these particular routes could be devastating..remember these people are travelling from other GF cities, and connecting to home, the cost structure needs to be re-aligned to allow the fares to be profitable, all Gulf-based airlines serve the same markets, so adjusting the fares is out of the question, once one leaves the market, it is immediately swamped by the remaining carriers who can "afford" to operate those sectors...loyal passengers are few and far between here, it's all about connection, if you don't have them, you lose...
