The BA route is worth considering, together with the FLYBE MPL scheme. Any form of sponsorship is worthwhile as a potential job is likely to follow.
If this type of route fails to materialise, choose a well recognised EASA ATO, and go full time. Ensure that you do a full MCC/JOC course post IRT. This is the most important part of the basic training for fixed wing ~ better option?
With a year to go at Durham, you have time to fully consider the best option for you. Your present age is not an issue.
