Hi,
With 100k I assume it is Upper Class?
I am admitedly a little biased being VS Silver FF and not flown Delta but I would choose Virgin over Delta as the service is pporbably better (flat beds on VS), access to lounge both at LAX, LHR and the revivals lounge at LHR on arrival ( dining before boarding) and excellent cabin service & in flight entertainment-PTVs and games) as well as a massage service on board.
Enjoy your cruise.
I've been to Phoenix/Scottsdale twice on holiday in the past two years and loved the city and area.Lokking forward to visiting it agagain this summer.
As this is a Delta forum I'm ready to be flamed!!
