Why on earth would we not apply john_smith? It's a speculative application. Easyjet have been extremely light on detail so there is no way of knowing at this stage if the type rating will cost £300, £30,000 or be "self-sponsored" by way of a bond and if there is even a decent contract on offer.
For me, and I imagine many others, it will have to be significantly better than my current employment deal to consider it. Perhaps that won't matter; maybe there will be hundreds of unemployed people with experience willing to sell their soul for a chance to fly for ezy, and maybe there won't. Either way, if I didn't apply I would have no chance at all.
