“Online registration will allow you to choose a convenient "We offer you a seat on the plane and also avoid the check-in line at the airport if you print your boarding pass yourself, are traveling without baggage, are not transporting animals, and do not require an escort," says a message published on the official Coral Travel website.
The airline's press service did not specify whether the new service would be a paid service. As a reminder, low-cost airline Pobeda introduced paid check-in at international airports on October 28. The airline explained at the time that this measure was necessary to avoid increasing ticket prices.
A little later, Pobeda Airlines proposed to the Ministry of Transport that they introduce a fee for registration at Russian airports, but was refused.
We also note that on April 25, it was announced that Moscow's Shcherbinsky Court had refused to cancel paid check-in for Pobeda Airlines flights at international airports.
