Hilton Hotels is enabling guests to print boarding passes for 18 major airlines at check-in/check-out kiosks within the lobbies of 37 Hilton hotels. Using the airlines' web pages, guests can check in for their flights, change seats, request upgrades and print boarding passes at the kiosk. There is no cost to the guest for this service. "By expanding the capabilities of our kiosks with a time-saving solution for flight check-in, guests will have more time for relaxation or other priorities," said Tim Harvey, executive vice president and chief information officer, in a statement. Hilton check-in kiosks already let guests view their reservation, check-in to the hotel, obtain the room key and view pre-arrival messages. At the end of the stay, travelers can check out at a kiosk by reviewing their bill, confirming or changing the payment method and printing or e-mailing a copy of the receipt. Hotel staff can assist, if needed, with the kiosks.
