Hi Sidari, I was on BA in March & the 23Kg sounds about right, some people were taking what seemed like VERY large cases on as hand luggage, and although the fitted overhead, it did mean that there was a lot of crushed bags squeezed in around them.
A colleague travelled Virgin from LHR to MIA & was allowed 2 x 20Kg luggage in the hold with NO excess charge, which may be useful if you're going on a cruise.
Have a great time,
Alan & Katrina
