Nah, FLL will definitely have an SQ cadre. Think rsv coverage for broken pairings like a diversion in the summer time due to FL thunderstorms, or if someone calls out sick getting to FLL. If a pairing like that should become broken in FLL, it could be a multi-day recovery. They would need to fly someone else down from BOS/JFK then put them on rest first before operating FLL LHR. They will want to protect SQ flying a little better than that.
