I came up with this question through another thread. Is the EMB175 or EMB190 a regional aircraft or a "replacement aircraft?" Should regional airlines be flying these aircraft, or should the mainline companies be operating them? Another question: What should the difference in pay be for a FO/Captain flying a 40/50 seat jet and a 70/90 seat jet? How much is enough and what is fair?

My opinion is that it is a fine line. Where do you draw the line between what is a "regional airliner" and what is a "mainline aircraft." Also, if your opinion is that these are indeed replacement aircraft, would it be acceptable for regionals to operate them if the pilots were paid substancially higher (whatever that means) than say a 40 seat jet pilot? I don't have the answers, thats why I was curious to hear what everyone thought.
