Thing is gentleman, certain full sectors are priced below profit making rates in order to compete with other airlines who are able due to their cost structure to operate them at lower fares, or at a loss just to maintain a "market presence", GF apparently have decided they cannot, or are unwilling to do this..
Then what choice GF has? What can be done to keep flying without losing?
I dont think its possible to fly in this region without losing, simply because of the competetion from many legacy and low cost airlines which dont care much about the cash.
It doesnt matter what do you do or what strategy you follow, its no way GF can make money, simply because nobody does and noboy is interesting in doing that in the region.
