Hi there cjf21
Haven't got too much info for you, as i'm on the flying stage of the course, but a few months away from the job seeking/assistance part. All I can say is that BA/Ryanair/Flybe are the main target airlines that graduates seek out and are airlines where the college could potentially provide some assistance. In the past few months Ryanair/BA/BA Citiflyer and Flybe have all visited the college, so graduates could be of interest to them.
With BA very few graduates go to BA and with Flybe I have heard of students gaining interviews and jobs, although I know of no actual numbers. The common opinion is that you're chances of getting into BA, BMI and probably Excel are greater at Oxford, but outside of these three airlines you're chances of getting a job elsewhere is about the same wherever you go. Of the students gaining interviews at BA and Flybe, these have been through recommendations.
Maybe someone having completed the course or nearer the end could update you better.
Cheers
