One other thing not mentioned is that if you are coming here needing a full 1000 hrs to upgrade, you will likely be senior enough as a CA to completely bypass reserve, even though FO reserve even in EWR will probably be 4-6 months, longer in IAD.
Furthermore, I don't believe we have classes for FO's anytime soon as we are very fat with FO's and lean with CA's.
Probably not until early to mid 2020 is one likely to be able to start, unless they are coming in as a DEC.
