A remote airline check-in system is online at The Rosen Centre Hotel in Orlando, Fla., allowing guests to check bags as early as 12 hours before a flight. A partnership between network provider ARINC Inc. and BAGS Inc. (Baggage Airline Guest Services) devised the system, permitting travelers to get boarding passes and bag receipts at the hotel for a $10 fee. The Rosen Plaza, also in Orlando, is also expected to begin the service.
