Though the FARs are same for the airlines, what is different is the amount of $$$. Lets face it safety costs money. Want a safer airline? Put cash into it. Regionals really dont put alot of money into safety sometimes. Since they make money by flying, if something isnt correct with the airplane for instance, there is a certain level of pressure to fly anyway. If a captain refuses, no big deal, just find a recent upgrade and he will do it. Ive seen this myself.
