Use Air Data - their Airplan 3 is a good system with a very good opmet/notam package however they are close to releasing their all swinging brand new system that they have been developing over the last 2-3 years but well worth the wait....I had a quick preview of the new system and it is quite something else mainly because they got all their customers on board and asked them what they wanted from their planning systems, they then listened and then implemented it and the results were amazing also its so cheap compared to others.
Virgin do use Phoenix but Air Data's opmet/notam package and were involved in the new system (so i'm told)
