Positive Identification, Recovery and Denial of Boarding
Travel is the transfer of people from different remote geographical locations between different time zones. Travel can sometimes be done by land, by automobile, plane, train, bus, bicycle, horseback, car, plane or any other way, with or without luggage and is either one-way or round-trip. Some types of travel include commercial travel, domestic, caravanning/hiking, international, cross-country, adventurous, backpacking, bicycling, hiking, mountain climbing, white water rafting, trekking, yachting and sailing.
Positive identification verification, known as PMI, is required for air passengers. PMI verification is required when international travel is required. This is to prevent any acts of foul play on the part of either the passenger or the airline that could result in a denial of boarding or a delayed departure. This PMI requirement is not applied to passengers who board with their own passports. When air passengers fail to produce proper documentation for verification, they may be turned away at the airport or turned down at the airline booking desks.
When a person boards a domestic flight, they are required to provide documentary proof of identity and citizenship. When a person boards a cargo flight, they will also need to provide documentation proving that the person has a permanent employment contract or other proof of income and financial capability. To avoid a negative test, it is advisable to provide electronic copies of documents and letters that can serve as verification.
