Cathay Pacific has confirmed it will shut down its booking system on Saturday 11th and Sunday 12th February as it upgrades its software.

Passengers looking to make an online booking or online ticket change are advised to do so by Friday February 10th “to avoid any disappointment” Cathay said earlier.

Those looking to request special meals, reserve seats, subscribe to notiFLY messaging, check-in online, or print e-tickets face a similar deadline.

The Hong Kong-based airline issued the following statement: “If you have an urgent query about flights leaving between Saturday February 11th and Sunday February 12th, please proceed to the airport for assistance.

“For non-urgent reservation and ticketing queries, you can get in touch with us via email at [email protected] or ask for assistance once you arrive at the airport.

“You may also want to follow us on Facebook or Twitter for any update during this outage.”

The airline’s flight schedule over the weekend, however, will be unaffected by the changeover.

Cathay Pacific chief operating officer, Ivan Chu, said: “Our current system has served us well. However, just as we upgrade the products and services our customers can see and touch, we must also update our technology behind the scenes so that we can support the continued growth of our airline and the expanding expectations of our customers.”

The new Altéa reservation and inventory system is provided by Amadeus, the same reservations system used by the majority of oneworld alliance carriers.  Cathay Pacific is a founding member of oneworld.
