Ebola has Dallas on edge: A middle-aged African-American woman was locked in the lavatory of an American Airlines flight from the Texas city to Chicago after she began vomiting. According to another passenger on the flight, she had vomited in the aisle and then was told she had to reveal all her recent travel and remain in the bathroom for the remaining 45 minutes of the trip. The woman’s carry-on luggage was wrapped in plastic. “If I had puked on the plane, would they have they done that to me? I’m a 60-year-old white woman with gray hair. No, they would not have,” said the witness, a University of Texas professor. Both of the American nurses who have Ebola took flights from Dallas after they were infected, but they are not believed to have been contagious at the time.
