I see many of you write about this KVS availability tool, cheapest fares, maximize miles, etc. So I thought I would give my question a go on this forum.

I am planning on this schedule:

20 jan 2006 AMS - SJU
6 march 2006 SJU - MCO
19 march 2006 MCO - AMS

The return dates need to be changeable for max. 100 euro pp and we're students (2 pax, minimum 6 months ticket, because we might stay longer than 3 months). A travel agency found a ticket in L class with US for 750 euro incl. tax. = $ 900. Do you guys know if this can get any cheaper? If possible could you guys give this itenary a quick check up?
Thanks a lot.
