Public awareness of risk vs cost
I've said this before on other threads, but I have been on the retail side of travel as well as airlines, and 99pc of the public ONLY look at the price. There will be one helluva outcry if an accident is shown to be due to too many cut corners/crew or engineer working hours, etc. , but I will bet the next day SLF will still be searching the net for the cheapest fare.
