Suppose Eleanor flies to Europe to seek the proper setting for her new historical novel. You want to let readers know she went to three different places and the fourth one is where the action picks up.
A simple paragraph can bridge the time from her leaving the United States to the moment of action: Seven hours after landing at Charles de Gaule Airport, Eleanor reached the Normandy Coast. After a fruitless day, she left for Zurich where she spent two days. Her Eurail pass took her to Berlin and finally to Brussels.
You need that paragraph of information to authenticate Eleanor's travels. Because nothing dramatic happens until she reaches Brussels, you can leave out three minor scenes. Don't take her through customs or have her struggle with French. Readers don't care. They want her to get to Brussels.
Spare your readers from details they don't need to know.
