I think that the post above addresses one of the most salient points: yes, there will probably be jobs available in the future. However, while training costs will remain absurdly expensive, the terms and conditions offered by airlines will be absolutely appalling.
First officer contracts will most likely be at the zero hour, minimum wage level with no additional benefits, and captains will be earning £60k. Why anyone would want to take on mortgage levels of debt to train for that is beyond me.
