I cant see any flight from BGI to BRS today/yest or BRS to BGI Yest - not saying there wasn't one (although that might be the case) there's a couple of flights listed from Bristol to other UK airports and then departures to Barbados from quite a few UK airports so maybe it went via one of those?
Also pretty sure it'll have been a 300 as i'm 99.9% sure from memory the TOM 200's have already left now and FCA didnt operate any without going to check.
