Just come back from Dubai - meet and greet offered to two of us in First. Good idea bused to a lounge where they take your baggage recalim ticket and passport then walked through immigration reunited with bag and taken to your car transport.
On leaving Dubai - special services at check in introduced me to a Maharaba Staff member who walked me through immigration (you essentially get to use the e'gate line) and then buggy to the BA lounge.
Lounge Staff said it was only offered to premier / ggl irrespective of which cabin they were in. Might explain why the CSD only spoke to two of us on the way out.
Wonder if they do it t Doha as well.
