Do you think Aer Lingus will run a similar scheme the same time next year?
You can never tell. Circumstances can change. When I was in school there were cadetships, fully sponsored, every year. When I left school I applied that year, didn't get in that time. No problem, try again next year. Only there was no next year or the year after and the cadets who got in when I applied ended up working all over Aer Lingus for years until slots came available. In an ironic twist four of them worked with me in the same job.
So just hope there's another competition. But makes plans for doing it all yourself.
