Not knowing the intricacies of the OAT/NJ scheme, at first glance it looks to me like your bet is safer at CTC - if in 12-18 months time if (when?) the much talked about recession hits and NJ don't need as many pilots as they thought (eg Tfly and FTE), will OAT do anything to help you find employment with an alternative airline? And if bizjets are your thing, there's nothing to stop you doing that out of CTC, who's to say they won't have a bizjet partner airline by then? Keep your options open, I reckon just about the only thing you can be sure of in aviation is that it will all be different in 18 months.
