Get an EASA Licence. A UK licence is of little value unless you can get a job with BA etc. Ryanair require an EASA licence and they are by far the biggest operator in the UK. Your no good to easyJet with just a UK licence as half their fleet is European registered. The present situation will not change, cooperation between EASA and the UK is just hopeful thinking by a select few.
Too many European operators based in the UK for me.
Checkout flight international for jobs, you need either a EASA or FAA licence for most.
