Hello,
I have a similar question and maybe you could help me sort it out.
I'am Airberlin Topbonus Gold and will flight from:
Milan Malpensa to AUH flight operated by Alitalia & issued on Alitalia stock
then from
AUH to SIN flight operated by Etihad & issued on Alitalia stock.
Do you know if I will be granted access to Alitalia lounge in Milan Malpensa & Etihad Lounge in AUH with my Airberlin status?
Thanx
