Half-pint... Does you regional jet you were flying have EFIS? If so, if you have more than 500 hours on the EFIS a/c, you should apply as a first officer, not s/o.
SW1, how much total time do you have? again, i think you should have applied as f/o as well.
Coz if you are more than 28 years old, and apply as s/o (irrespective of how many hours you have) they will say no coz thats the age limit for s/o. If you got 2000TT and you got 500 EFIS hours, you can apply as an f/o. If you don't meet any of the criteria above, then your application will go into the bin...
Hope this info helps..
