multi-city flights USA

Looking to fly from London to detroit then to miami then to london. But I want all direct flites and can't seem to book this online .  Anyone have better luck

If you book with a commercial site like travelocity or expedia, thee is usually an option to select "multi-city" on the homepage before you enter your destination, dates, etc.  DH did this with expedia, he flew London to Las Vegas, then LA to London, same price as a regular return flight.

I have tried but can't seem to get a direct flite each location

I do multi-city lots, but I book my overseas flights separately. This trip I am traveling from London to Las Vegas to NY to London, so I booked LON --> LV  NYC --> Lon on Virgin, and then LV --> NY on JetBlue.

I wasn't worried about connection times since I'll be spending a couple of days in each place, so I'm not sure how to accomplish this, if you need to make flights with small windows between them.

Have you flown direct to and from those places before, blondshania?  Maybe there just aren't any direct flights from London to Detroit   

I believe the problem is that the only non stop flights from Miami to London are on Virgin and it seems like Virgin flights arent always listed on Travelocity/Expedia/etc.  I found direct from LHR-DTW and DTW-MIA, but then was only offered a flight with a layover from MIA - LHR.

Update: ...upon further research thats not true at all, but Travelocity is only offering me flights on Northwest once I have picked the original Northwest flight from LHR to DTW, so maybe they wont let you mix airlines?  But that doenst make sense either, really... You may just have to call whatever website you'd like to use and book it that way.  Or just book them seperately.  You wont save any money by booking them all at once.

Update #2:  Success on Expedia!   Northwest from LHR-DTW, Northwest from DTW-MIA, American from MIA-LHR.   You have to click "choose individual flights" at the top of your results and pick each flight seperately.  Dont let them bunch the flights together for you, and you can get all non-stop flights.
