MANILA - After Cebu Pacific announced that it canceled dozens of flights from April 28 to 30, the budget airline said it will cancel more flights until May 10.

In a statement released on Monday, Cebu Pacific said it will be canceling 58 round-trip flights until May 10, 2019 as part of its "ongoing effort to improve on time performance and reduce inconvenience to our passengers."

The airline said those who are affected by the cancellations may opt to:

1. Rebook flights for travel within 30 days from original departure date, free of charge
2. Reroute to / from alternate airports for travel within 30 days, subject to availability of seats
3. Get a full refund
3. Place the full cost of the ticket in a Travel Fund

Cebu Pacific said passengers on cancelled flights will receive one round-trip travel vouched which can be used for future flights.

Cebu Pacific earlier released a list of flight cancellations from April 28 to 30.

The "unprecedented" flight disruption was due to various factors, including several damaged aircraft and heavy traffic that prevented flights from taking off and landing on time, the country's largest carrier explained.

"To create space in our schedule for operational recovery, minimize rolling delays and give passengers the chance to make alternate travel plans, we have to temporarily reduce the number of our flights given the current operating conditions, particularly in our Manila hub," the airline added.

The Civil Aeronautics Board said it is investigating the incident.
