Hi again galdian, i must be phrasing this wrong. i would only apply and go for a DEC on the A330, as advertised.
For me personally, getting a 330 job would be a better position as i am on medium haul at the moment ( this is what i mean by upgrading, i mean it like going up one step in my personal situation).
If for any reason i was to go there, pass the selection, and be assigned to the 737 instead, then i would simply not take the job.
sorry for the off topic
