Grüße dich Mightbe!
Unless I am mistaken I think I have worked out who the mother and daughter companies are and if I am correct then I am currently one of those people who left "mum" for the "daughter 6 months ago!
All I can say is take the opportunity! This place is fantastic and it is great to see another company and to fly this fantastic aircraft. You would be crazy to give up an opportunity like this!
You can not rely on "Mum" at the moment with her forcast especially with what I believe will happen to the other "daughter" company in your country (i.e. this daughters sister) and their pilots! I think you may be optimistic with 1,5 years!
Don't be greedy on seniority at the mother comany... you may lose a bit there if you come here, but you will lose a lot here if you stay there!
Send me a personal reply and I can answer more questions you may have. ..
PS The decision who is being selected by the daughter will not be made until the 10th! I know the chances are good but don't forget it is not certain yet...
Hope to get an email soon...
