Pretty soon paper tickets and security documents will be replaced when traveling.

According to Bloomberg, the International Civil Aviation Organization met last month in Montreal to discuss how they can replace paper travel documents with digital travel documents.

This new effort in implementing biometric data is an effort to ease gridlock when traveling.

The World Travel & Tourism Council says there are about 53 biometric systems being used by the travel industry — this includes airline boarding and hotel check-in.

For example, British Airways uses facial recognition at their boarding gates in New York, Los Angles, London, and Orlando.

Another example is New York-based private security screening company Clear — they use fingerprint and eyeball scans when moving travelers through security checks.

The global travel industry is determined to reduce travel gridlock because of the predicted passenger growth from 4.6 billion in 2019 to 8.2 billion in 2037.

Airlines are also working on a system called One ID so travelers will not have to keep up with multiple documents.

The CEO of the International Air Transport Association, Alexandre de Junlac says, “with One ID, passengers will no longer be subject to repetitive document checks from check-in to the departure gate.”

Junlac also said, while speaking in Athens at an aviation data symposium, “air travelers have told us that they are willing to share personal information if it removes some of the hassles from air travel, as long as that information is kept secure and not misused.”

According to Bloomberg, Delta Air Lines said last month they would increase racial-recognition boarding on international flights at 49 gates in Atlanta, Minneapolis and Salt Lake City.

Delta Air Lines had been using facial recognition since last fall in Atlanta and 72% of passengers in a survey say they preferred this technology over traditional boarding.

Before the end of 2019, some airports and airlines will start tests on replacing paper travel documents with digital travel documents.

The routes being tested are London-Dallas, Amsterdam-Aruba, and Dubai-Sydney.
