(With apols Mods if this should be posted elsewhere, feel free to move) … about to change an existing Avios open-jaw TATL to include a segment between MIA and LGA/JFK as its only 18k plus £9.40 … BA site says it’s a hand baggage only fare.

I’m only silver and unclear if I get any checked allowance … can anyone help with knowledge or by pointing me at the page to read please ? (And TIA)
