Goodbye boarding pass, Emirates (in Dubai) will no longer print tickets
Emirates goes digital, phasing out paper boarding passes for flights out of Dubai

After saying goodbye to physical frequent flyer cards. airlines are about to say goodbye to another "piece" of paper, Emirates is the first airline to announce the divestment of paper boarding passes, at least initially only for flights departing from its Dubai hub.
In this article:
Emirates will require most passengers departing from Dubai to use a mobile boarding pass instead of a printed paper version, from May 15 onward. Passengers checking in at Terminal 3 will receive their Mobile boarding pass via email or SMS. Passengers checking in online can upload their boarding pass to their Apple Wallet or Google Wallet or retrieve their boarding pass on the intuitive Emirates App. The checked baggage receipt is also sent via e-mail directly to passengers or available in the Emirates App.
This initiative will significantly reduce paper waste while offering a convenient and fast digitized check-in experience for passengers departing from Dubai. It reduces the risk of lost or misplaced boarding passes, giving passengers peace of mind while traveling.
The mobile boarding pass can be used throughout the trip: at Dubai Duty Free, at security checkpoints, and for boarding, simply by showing the boarding pass on the phone. Emirates agents and airport staff will simply scan the QR code on the mobile boarding pass as passengers walk through the airport and board the plane.
Some passengers may still require a physical boarding pass to be printed., such as when traveling with infants, unaccompanied minors, passengers requiring special assistance, passengers on subsequent flights of other airlines, and all passengers traveling on flights to the United States.
In case of problems there is still the paper ticket
The option to print a boarding pass is available upon request to Emirates agents at the check-in counters if passengers do not have a mobile device or are unable to access information on their devices for reasons such as: power battery depletion, system failure or technical problem, delay in message delivery, or inability to access Wi-Fi, network, or a data packet.
