A system and method of booking an itinerary on at least one of a multiplicity of host environments include a plurality of host adaptor modules. Each host adaptor module is configured to interact with one of the plurality of host ticketing environments. A booking engine is provided for receiving commands related to booking the air travel itinerary and determining an appropriate host ticketing environment for processing the commands based on a number of predefined criteria.

The host adaptor module receives the command and issues the command to said first host ticketing environment. The first host adaptor module in turn receives a response from the first host ticketing environment and determines whether the response comports with an expected response. If the response does not comport with the expected response, the booking engine identifies a second appropriate host environment for processing the command and forwards the command to a second host adaptor module associated with the second host ticketing environment. The second host adaptor module then issues the command to the second host ticketing environment.

A system for luggage self-tracking / identification during air travel involves a programmable, wireless LAN active transceiver preferably located inside each piece of luggage, with controlled access to the airlines' luggage tracking networks. Prior to a flight, each transceiver is loaded with the passenger's itinerary, and logged in the airline's network at check-in. Each transceiver is uniquely identifiable by the luggage tracking network. An example of a preferred identifier would be the utilization of its Medium Access Control (MAC) and its alphanumeric serial keyword to provide unique and secure registration / identification of the transceiver in the airline's network. During the trip, which may include different stopovers before reaching the final destination, the transceiver is able to automatically compare its programmed itinerary with its current location via wireless access to the airports and aircraft wireless LANs. In this way, the transceiver is able to notify airline personnel if there is a disagreement between its programmed itinerary and its current location, thus preventing misrouting. The transceiver's itinerary can be wirelessly re-programmed by airline personnel / network to account for flight changes or delays. Finally, the transceiver has an internal timer that starts counting down from the expected “total traveling time”, accounting for flight changes or delays. If this timer elapses without the itinerary being complete, the transceiver connects to a wireless access point (hotspot) to report itself as a missing luggage, avoiding a worldwide tracking initiative and speeding up recovery time.

A tractor-trailer system uses aerodynamic principles to use crosswind to its advantage. The system has a curvilinear duct by having a attaching a convex body on the trailer front and a concave body on the back of the cab. When a cross wind enters the gap, it creates a negative pressure (compare to ambient) on the convex surface (trailer front) and a positive pressure on concave surface (back of the cab). Both of these pressures will help reduce the drag. Further having the crosswind flow smoothly can lead to less turbulence intensity in the gap, which can help in improving handling qualities of the system. There is a similar situation both for drag as well as handling qualities can be given for the air traveling in vertical direction (even at zero cross wind).
