Think most Training Captain's on the larger airlines flying Jet Aircraft will be on 100k+ (inc benefits). Likes of BMI, Thomas Cook, BA, Virgin etc. BA defo don't need to be even a Training Captain - all on seniority from what I hear... as mentioned previously an SFO, longhaul with 10-15 years service is going to be on good money.
I was a contractor in Financial Services before piloting. Helped me fund the training but given the lack of piloting jobs about, sometimes I can only but reflect with a slight twinge of regret at what i've left behind - hopefully will all come good soon. The point - definitely more lucrative jobs out there if money is the objective. Anything contract/consultant related is big bucks... IT consultant, Finance Consultant(specialised) can get you anything from £300 - £1000+ per day. Work can be irregular though and sometimes hard work - remember with piloting you may be working 25% the number of hours of other types of job.
