Gatwick 747 Barbados

Hi
Anyone know how many upper reward seats are available on these flights?
Logged on first available date for Barbados- London on 2 December and only 1 upper available. I know it is only a small upper cabin, but is it normal to only have 1 reward seat?
Always flown Dubai and Miami before and they have lots of upper reward seats.
Thanks for the help.

There's no set number. It depends largely on how many seats VS think they can sell in each fare bucket. And I'd have thought Barbados in Dec & Jan isn't very hard to sell.
