You have received conflicting answers. This IS a difficult question. Yes, transit visas no longer exist, BUT there is a new process for foreign nationals transiting through the United States. See website below. Enter her nationality as from El Salvador, Transit country as U.S.A., destination as U.K. and clikck to see passport and visa info. It explains that she must report immediately to the Federal Inspection Services area. These passengers are then taken to a separate lounge for foreing nationals in-transit through the U.S. No U.S. visa is required, but they do have to go through the inspection, then wait in that lounge.
