I did this route last weekend, and you'll get pretty well the same CW experience in the air as most other BA flights, but the CW ground experience at LGW and MCO is somewhat lacking. Fast track security at MCO is a total joke, and be prepared to be stuck behind large families that'll argue with TSA as to why the can't bring a liter of shampoo in their carry on etc (happened right in front of me!). Overall, site back, relax and enjoy yourself!
