The best thing to do is to ring the job centre at manchester airport (it's located in commonwealth house), get the number through 192. Then ask them to send you a complete list of the airlines based at Manchester.Then send everyone of them your CV, covering letter and full length photo. You could check out the individual companies web sites for more info.This is how I began and i have been flying now for two years.
Send them in asap 'cos summer recruitment will have started.
Good luck and hang in there it takes time.
