FNPT/not FNPT trivia aside, The JOC that oxford offer is really just a cherry on the top of a well iced cake. The MCC is all you need full stop. I guess, to be better prepped for a sim assesment at an airline interview it may be a bonus, for alll you know, the sim assesment might not very well be in a 737! FTE's cheaper cource with accomodation icluded isalso another option, smaller class sizes nice weather etc. etc. Their JOC is at an extra cost and is done in a Buisness jet sim, the Hawker I believe...which is apparently programmed to handle like believe it or not.... like a 737!
If you are going integrated, don't do it to just 'put a check the box', yes you've done the course so you expect a job. Do it well. Like Kick ass and kiss some
(maybe) get good grades, and as many 1st time passes you can get. Then those "orchestrated" job offers may just come your way, or at least, a letter of recommendation from the CFI.
