My first reaction was to question if you had any roundtrip tickets originating in Europe. The USDollar is *WEAK* and may affect the outcome of the pricing.
Secondly, did any of your 2005 trips use any coupons for discount air travel or if they were included in a hotel/cruise package?
Finally, have you resorted to nesting itineraries within itineraries yet? Departing from a cheaper point does have an advantage if you can plan far out.
