'when they can make it stick' Indeed 20driver, indeed that is the acid question.
I am sorry to be a pessimist but, having seen recessions before, by the time this one is in full swing people will not be picky about paying another $/£ 100 but can they get a flight at all? Aircraft and crews will be cut back very rapidly and then some carriers will have no choice but to close their doors. Capacity will be reduced and then fares will rise to realistic levels.
What will then be left between the old and new style carriers?? No one knows as this is all uncharted air space. Many uncomfortable times now on the doorstep.
