There's an ex-CDG J fare to MIA that can be had from c€1520 (approx £1290). Departure dates around the end of June/start of July
and return before the 15th. There's been better in the past but looks a decent fare. Flexibility looks limited as well.
Maybe worth looking further into CDG for the US as JFK is available for c€1320 (c£1120) around the same time. Better flexibility on this one.
