Aeroflot warns of potential flight cancellations due to a nationwide booking system outage, affecting schedules across its network.
MOSCOW, Jan 26 (Reuters) - Russian airlines were forced to cancel some flights on Monday due to a nationwide outage of the Leonardo booking system which has since been fixed, the transport ministry said.
All major Russian airlines, including national flag carrier Aeroflot, had earlier warned of possible schedule disruptions, including changes to departure times and flight cancellations.
The transport ministry in a statement did not name the affected carriers or destinations, but said officials would meet later on Monday "to analyse what happened and minimise the impact of the disruption on passengers."
Russian state industrial conglomerate Rostec said that the problem in the Leonardo booking system had been caused by an "internal technical problem" at its provider, Sirena Travel.
Aeroflot was hit by a major cyberattack in July last year, disrupting travel across the world's biggest country. Two Ukrainian hacking groups claimed responsibility for that attack at the time.

A booking system is a software application that allows customers to reserve services such as flights, accommodations, or events, managing schedules and availability.
Flight cancellation refers to the situation where an airline does not operate a scheduled flight, often due to technical issues, weather conditions, or operational constraints.
Passenger guidance is the information and assistance provided to travelers during disruptions, helping them understand their options and next steps.
