One day had a B727 flt from MIA to KIN. APPROACHED A 200+ MILE LONG LINE OF CELLS AND MANAGED TO FIND ONE NARROW gap to get through. When we got to Kingston they were sending us back the same way with minimum fuel. I told them I wanted to go over Cuba and arrive from the south to avoid the line. We took a delay for more fuel for the reroute.
We always were within close range of a B757 from Montego bay to MIA so out of curiosity saw how their flight went. They diverted to Orlando because of their extensive deviations and for fuel reasons landed in Orlando. They were hours late. Going through gaps in the line like we did wasn't how I wanted to operate but it was the only way not to turn around. Knowing what you are facing you can fuel up and avoid having to make that decision.
