You have got most of England and Wales covered in 90 mins from MK. Start by trying places like Sywell, Coventry, Wolverhampton, Sleap. Once you have a bit more confidence perhaps see if you can get a more experienced pilot to do a trip with you to somewhere like Barton, which has a Grass strip and lots of controlled airspace, as what might seem like a complex transit usually isn't unless you start trying to go through Manchester, Luton, Gatwick etc. enjoy your PPL
