The days of walking to the gate with only a credit card to check-in, are over. The US Department of Transportation now requires travelers to present a printed airline ticket on the designated airline OR a printed e-ticket confirmation or e-mail itinerary which includes passenger name, identification number, flight number, date and either a confirmation number or ticket number OR a printout of a Web site confirmation, if the flight was booked via an airline Internet site. If a confirmed passenger is not in receipt of one of these documents, they can request a printed confirmation at the appropriate airline’s check in counter. Passengers without one of these documents will not be allowed to board their flights. Only ticketed passengers will be allowed to proceed past airport screeners to boarding areas under the new heightened security procedures.
