Regionals are a dying breed. What will/has caused this?

1.) Consolidation of 3 legacies
2.) Flying being shifted back to mainline aircraft (which is great!)
3.) 50 seaters are out and being replaced by 70-80 seat aircraft. When this is
done, 1 70-80 seat aircraft can do nearly what 2, 50 seat aircraft can do.
Hence less pilots needed.

What is good today will not be good down the road. This business is ever changing. Go to a place where you can get TPIC time the fastest and then get out. TPIC is TPIC. For the most part, airlines that you are aspiring to go to down the road do not care about which airline you came from.
