Grounded,
Agree, plenty there for everyone if you look hard enough. In my case however, the key word is "flexible". Sometimes we will change timings/flights for a ticket three or four times for a trip..before and during so we have to be able to do that without penalty which takes away the opportunity to use most consolidators.
I think our deal with VS is pretty good on the basis it is a true discount on the fare..in other words: normal miles accrued, normal transport available and full flexibility. Mind you, we are putting a very large amount of business to them.
