Ill take bait... is the job of FO on a regional crj, 145, 175 any different than the job right seat on the 73, 190, bus... I'll argue we are all ATPs. Upgrading didn't mean im strong.. i was willing to take extra responsibility in trade for being on the bottom of the list for a small pay increase. Ive worked with many of our career fos.. many of them are doing great at mainline now... many of our career fos are excellent aviators and have valid reasons for not upgrading.
Now if the WOs paid us properly for left seat work than that is another story..
