Don't know, but you are in the right place. They seem to have more Spanish pilots than Brit
Don't know where you got that information, I am pretty sure there are a few Spaniards however there recent intake - I believe 6 FOs this year - were all Scottish based instructors. Not sure if there is any further expected, however all these guys were sitting in a hold pool for a considerable time. I know one of the fortunate 6 personally. He enjoys it immensely. He may be along here soon to shed some light regarding future positions.
