The airline industry is a pretty rare one in which the laborers, in this case the pilots, have to be very highly trained and skilled and as a result are very hard to replace with competent personnel. The quality of the pilots can have huge impact on the operation of the company unlike any other, if they aren't good the main cargo (people) can be killed. And again, unlike almost any other industry, it can have an outsized impact on the company (regulatory, financial, etc.) and its survival. The quality of the pilots is held to a high standard in the US and western Europe and it is evident in the accident rate for the airlines in those regions, especially when compared to many airlines in other parts of the world. I can point to scores of accidents, many of them very recent, where inadequate training, inexperience and standards cost hundreds of passengers and crew their lives and the vast majority of those more recent accidents were in countries and airlines that are substandard.
The scheme that NAI has set up is one that is ripe for the development of substandard pilots with minimal training and qualifications and the subsequent safety issues that will almost certainly result. The average paying passenger isn't going to care until one of their airplanes falls out of the sky but the chances of that happening with the type of aircrew NAI is planning to employ are a lot higher than I would be comfortable with.
You're making some good points. I completely agree that being an airline pilot requires more training and skill than working at WalMart and all that, but I think that's beside the point. The purpose of a labor union is to serve the best interests of its members. In some cases, the best interests of the union members will be antithetical to that of the consumer.
I think there may be some hyperbolic rhetoric here though in terms of safety. Discount airline flights aren't exactly falling out of the sky and it would actually be an interesting conversation to have if we could remove emotion from the discussion. Is there a reliable metric to use? I'm totally not familiar with this world; but it would be interesting to see a researched stat that could predict, "if an airline pays pilots $xx,000 less per year, that airline will see an increase of y% catastrophic mishaps."
