James asks a reasonable question, and you guys come in like Rambo guns blazing. Your idealistic views on getting experience by instructing/flying a Tiger Moth are lovely and will stand you in good stead in the future but don't galavant in like a new romantic thinking you're morally and ethically correct for doing so. Horses for courses and some people need a little bit of nurturing before they become enlightened towards the better* approach to pilot training..
*in my opinion, for what it's worth
James, back in the halcyon days (circa 2005-7), you could have gone away and bought a type rating and pretty much walked into an airline job. Not anymore though. Things have changed and you'll largely be regarded as a fool to blow your money on a type rating without any chance of getting time on type. Research this well and refrain from letting the TRTOs dupe you into thinking that buying a TR is good for you, it isn't.
MCC - There are some good MCC courses around which don't involve giving your money to the big corporates like CAE/OAA. The CTC MCC option (otherwise known as AQC, essentially a MCC and JOC combined) might give you the chance of getting your name on a long list of people waiting for a job. The door doesn't open very often for modular candidates to apply for the ATP scheme so timing is the key. Ryanair for example suggest you MCC with one of their partner Type Rating Training Organisations (TRTO) but this doesn't exclude you from doing an MCC at somewhere like Stapleford and then applying to Ryanair. I know one or two people who have MCC'd at Stapleford and passed the sim check/interview for Ryanair.
