WASHINGTON -- US Airways said starting June 1 passengers better check in earlier for their flights or their plane will leave without them. Under its new "Travel in Time" procedures, the carrier said passengers are required to check-in with their baggage at least 30 minutes before departure, instead of the current 20 minutes. They will be required to be at the gate at least 15 minutes before their flight, up from 10 minutes, or the airline will give their seat away. US Airways also said it will close the aircraft doors five minutes before departure. "This helps assure an on-time performance," a US Airways spokesman said. "Passengers who don't check-in on time will have to take a later
flight."
