LGW TO ST LUCIA

Hello, I am a new member and am travelling to St Lucia in two weeks on honeymoon. I will post a TR when i return and always read the reports with interest.
My question is I noticed that todays flight to St Lucia was delayed by 8 hours. Does anyone know why this was and are delays common on this route. I ask because i have booked a helicopter flight to the hotal the other end and they do not fly past a certain time, so if we are delayed we woulld miss this.
Can anyone help.
Also we have booked PE on our fist virgin flight. Reserved seats upstairs. What can we expect on the flight?
cheers
