How far into the pilot training are you - i believe that CTC McAlpine are looking at self funded CPL's
But to be the bearer of bad news your too old at 27 for most sponsorship CPL courses! i should know i'm 29 and can't get in!
NATS i believe is 30 unless you've prior experience in an aviation background (hence the first question!)
Not too sure about the cost for self funding the ATCO route but i think your looking in the region of 30K!
