Frankfurt Airport's (FRA) AIRail Terminal is directly adjoining FRA's Long-distance Train Station. The close physical proximity to the railway shall ensure tight integration of air transport handling facilities in the high-speed rail network to allow passengers to connect between the different modes of transportation with maximum convenience.
Travelers can check in for their flight in the AIRail Terminal immediately upon getting off the train. Both Fraport and Lufthansa operate check-in counters there for forty airlines.
In addition to sales and logistics facilities (DB - Travel Center; Fraport – Fly Baggage room), the AIRail Terminal provides important amenities of Lufthansa's AIRail Service (e.g., Baggage Drop, Baggage Claim, Baggage Tracing, Customs).
Operating successfully on the Frankfurt – Stuttgart (since May 2001) and Frankfurt – Cologne (since May 2003) routes, the cooperative AIRail Service ("train to the plane") offered by Deutsche Lufthansa AG, Deutsche Bahn AG, and Fraport AG, also started serving the Frankfurt – Siegburg/Bonn route at the beginning of November 2007. According to the "seamless travel" principle, travelers can check in at their central train stations to receive the boarding passes for their onward flight from Frankfurt Airport. (At the Stuttgart and Cologne stations, the check-in counters are at the train station; at Siegburg/Bonn, check-in has to be done via the Internet).
In the AIRail Terminal 
(233 KByte), AIRail passengers check in their baggage at the LH Baggage Drop counter (233 KByte). Vice versa passengers arriving from a flight and traveling onward by train can claim their baggage and clear it through customs at the AIRail Terminal.
The strategic purpose of the AIRail Service is to move short-haul domestic air traffic to the rail in the long-term. For example, Lufthansa has already suspended all flights on the Cologne - Frankfurt route since the end of 2007.
