I am blowing a fuse trying to work fit my trip into my budget - I want to travel from Miami to germany then london back to italy return to london ( prefer to fly ) and keep the price down.. is there ONE site that can cope with compictaed trips? or come up with suggestions for best prices?

Hi Play,

It might uncomplicate your trip if you flew Germany to Italy to London.

If you plan to fly throughout you could probably use one of the "usual" sites such as Expedia and use the "multiple destinations" portion. However, those sites generally cut out the so-called "discount" airlines such as Southwest in the US and RyanAir, EasyJet, AirBerlin, etc., in Europe. I suspect someonme will give you the website for the "Fly Europe" thing for which you buy coupons.
This is a difficult question to answer since you do not say if you want to fly on all the segments mentioned or if you are, as Ira suggests, willing/flexible about the order of the cities.
If you get totally frustrated despite the helpful recommendations you receive here you might want to resort to an actual TA and let them do the work for you.

To fly cheaply in Europe, perhaps you could try return tickets from Miami to London, then take the advantages of non-frill arilines Departing from London for other destinations. I have done it for few years.

The following sites are for cheap flights: www.ryanair.com
www.easyjet.com
www.flybmi.com

This ia a case where a travel agent might be helpful. Last year we flew from DFW to Frankfurt, traveled around Germany and Austria, then flew from Frankfurt to London and back to DFW. I did this trip myself and found great airfares, but it does require a lot of time and patience to search and check out all the details.
