Cheers for the reply guys.
We booked up just normal coach class in the end from LHR. Was around £547 to Dubai which is on the expensive end but this is the problem when Mrs.SgtRyan works to the school year...oh well...it is what it is.
We were going to go J class from BRU as that would have only been £1150 each which is a bargain, but then there is the extra expensive of getting to BRU and again, due to the time of year the Eurostar was not cheap nor were flights so sod it...just go normal.
Cheers for the advice anyways!
