As far as I was aware the only school in the UK that even came close to offering career support was OAT. Going on past experiences of ppruners posting on these forums this service had been focussed more towards the integrated students and only then the cream of the crop which the airlines could hand pick. As most people will be aware OAT have a new programme but you pay more for the priviledge and still need to make the grade to give yourself a chance in anycase.
If it is networking for possible job opportunities then there are some schools that have "traditional" links with airlines. There are others where you can even by trained for your IR by training captains from the likes of the majors. None of this will guarantee you a job though. Had never heard of EPTA having career support or ways in to jobs.
