There is no loyalty among operators,
Thats not strictly true, I know what nexts boss personally, have flown for him as well and I would say he IS loyal. Having said that, he is NOT making his money in aviation and just uses his airplane as a business tool. IF his main business would go down dramatically, the aircraft - and what next - would be gone. Same at my place, the aircraft wa sup for sale when the company was in financial trouble.
Many operators are living hand-to-mouth, there is always the sword of damocles over ones head working for them. Wasn´t Netjets and the top 153 more a tax/regulations issue ?
