The majority of the new benefits have been available at CWL for a while now, except for the business points and the ability to alter the return journey on the day of travel free of charge if it's earlier or £35 if it's later.
The problem with this at CWL is that it wouldn't be possible for the business passengers to go on a later or earlier flight because there isn't one as theres only twice daily to EDI, BFS and only once Daily to GLA. (Except for fridays where EDI is 3 x daily)
So really not much of a change for CWL. What would the benefits be for the points?
