Sorry if that was already answered but I couldn't find it.

I'm planning a little familly holiday for 11 of us and it will be my first time doing group booking so I wondered a few things:

• will I get tier and avios like a normal booking?
• will I still have my silver benefits (priority security, boarding, luggage, etc) ?
• normally (for a classic booking) some of these benefits apply for everyone in the booking, will it be the case for a group booking as well?
• if I understood correctly BA will manage where we seat, does it mean I just won't have a choice at all? for example picking exit rows would be good ... (I see on expertflyer it is still available)

If any of these are noes, is there a real advantage using a groop booking over making 2 different bookings and being able to get all this?

Thank you
