Go British Air. The nonstop flight is a huge bonus as there are very few such flights to Europe from Pittsburgh. Study the Underground and use it for transportation while there. After you’ve seen the most famous London sights, visit one of the smaller museums, like the John Soames Museum or the Leighton House Museum. Have a drink at the bar on the top floor of the National Portrait Gallery.
