Hello together,

I'm traveling from Frankfurt (FRA) to Kilimanjaro International Aiport (JRO) with Emirates (booked via Emirates).
First leg FRA-DXB is with Emirates. Second leg DXB-DAR-JRO is operated by flydubai. The overlay time in Dubai is 8 hours
I will arrive in Dubai at Terminal 3 and the second flight goes from Terminal 2. I'm priority pass member.

Reading reviews the best lounge for Priority Pass at DXB is the Ahlan Lounge at B. The priority pass website says "only with Emirates flights".

Will I receive an Emirates boarding pass for both flights or will I receive two different boarding passes (one Emirates, one flydubai)?
And is it possible to get into the Ahlan Lounge at B with my priority pass for this travel?

If this doesn't work, I think the better lounges are at Terminal 1 (Ahlan, SkyTeam).
As far as I know it's no problem to walk between T3 and T1. And these lounges also have no restriction on PP website.

Any additional advice?

Thanks for your help.
