Go airlines - forget bizjets
In the UK, if you want a job, FORGET BIZJETS - no bizjet operator will offer you a job with low hours in UK !!!
CTC is probably your best option unless you are willing to get MCC/CRM etc and apply to all airlines, then wait ! Problem is, CTC is fairly expensive.
CTC have a scheme called the ATP scheme - basically, if you get accepted on to it (V stringent application procedure), you do MCC, CRM and get about 30 hrs in 737 sim. during this or just after, you'd be 'placed' with an airline with whom you'll get your type rating and commercial experience. CTC set a period of 6 months during which you're 'on-line' with an airline. After this, the airline will most likely offer you a permanent contract (No one has not been offered a full contract to date).
If you graduate from the CTC course, you get a job - 100% so far !
I believe it's been running for nearly a decade as well !
If you want to increase your opportunities and insist on going your own way, get eith er a 737 or A320 type rating. You'll not go bigger on low hours and they are the most common type.
Many operators recruit in some form or another on to one of these types through out UK !
For example, myself, now flying 737s due to CTC, mate starting with BA 737s, another mate A420 with BA, 3 to Easyjet o 737s (due to A319 orders, all 3 now booked on A319 courses therefore 2 ratings in less than 6 months), 757 monarch (through CTC), Thomsonfly/Britannia 757/737 etc. etc.
757s are starting to move out or go freight only - give that type a miss !
Basically - go to CTC, if unsuccessful, get 737 rating (both classic and NG if poss).
Good Luck
