tO have a degree is better than none...fact.
Having said that there is no point going to Uni if there is zero
motivation or desire for the subjects to be studied.
If you start flight training and go on to geta job you can always study your degree by correspondence.
Airlines are increasingly looking at pilot employees who do have a higher education.
Why not take a year out and travel which seems very common
among the poms.
Some life skills are better learnt at a younger age away from the aviation enviroment.
Having said all that only the lucky people inlife know what they really want to do and if the opportunity is there to start on your
chosen career then go for it.....lucky you.
