Uni might seem like a safer route as besides obtaining pilot license it also gives me a university degree, which going to a flight school doesnt.
Those university courses such as 'Aerospace Engineering with Pilot Studies' give you a bit of aerospace engineering and a bit of pilot studies, neither of which will get you a job either as an aerospace engineer or as a pilot afterwards.
As has been mentioned before, set your sights properly: If you want to be an aerospace engineer, then go to university and do proper aerospace engineering course (
without the 'pilot studies'!); If you want to be a pilot then go to a flying school and learn to be a pilot. But remember all along that getting either of those qualifications will not mean that you will necessarily get a job in that field,
that (trying to get that first job) is where the really hard work starts...
And remember that in either field you should expect to work up from the bottom: to start with don't expect to be either a Boeing/Airbus design engineer or a B747/A380 first officer. If you expect to start right at the bottom you are far less likely to be disappointed and you will appreciate it a lot more when you eventually do work your way towards the top. (Far too many kids expect to get really top jobs straight off just because they 'now have the qualifications'!!)
