True skirt steak is from the abdominal area of the cow (hangar and onglet come from a similar area). It is tough but deeply flavorful. Depending on the type of skirt steak, you need to remove a membrane from one side, which requires decent knife skills. Skirt steak needs to be marinated with a tenderizing marinade and sliced against the grain. It is the ideal cut of meat for dishes where meat is marinated and then either cooked very hot and sliced, or sliced and then cooked very hot. For example, it is a much better fajita and Asian stir fry cut than flank steak. It also has enough membrane and fat to be cooked in braises.
Flank steak is also from the belly of the cow, but farther back. It is not-infrequently-mislabeled as skirt steak, particularly when it is cut very thin. It can be labeled as London Broil when cut thicker (though London Broil can also be an entirely different cut). It is not as flavorful as skirt steak but is leaner. You normally want to grill, sear, or broil it. It is a decent option for cooking between rare and medium rare, slicing very thin, and serving on top of a salad, for example a Thai beef salad or a pub salad with fried onions and blue cheese. Some people think you can braise it well, but I don't agree. I think its major selling point is that it is an economical and relatively healthy cut of meat.
Flat iron steak is a chuck steak cut from the shoulder of the cow to look a bit like a skirt steak or flank steak. The marbling in it allows it to be tender enough that restaurants can get away with cooking it as they would other grilled steaks and serving it unsliced. It is used primary by upscale restaurants as a way of offering a <$30 steak option on their menu. I like this steak, but it is not my first choice for home cooking, both because restaurants hog the best of it and because its already possible to serve large cuts of steak at home for less than $30 - just buy some strip steaks and sear them.
