TBH if any charter holidays as soon as next summer to Florida will happen is still anyone's guess.
I note you are booked and have BRS-SFB flights which have now seemingly disappeared.
Your best bet is to call your Travel Agent, and/or TUI if you booked direct, to confirm what is going on, and have you been rebooked, or is your holiday now cancelled...
My understanding was that SFB is being withdrawn and TUI will now fly into Melbourne Orlando airport down the coast but not until 2022.
This change was to better serve TUI's Marella Cruise ship passengers joining.
I doubt that sadly many cruise ships will be running either next summer.
