Philippine Airlines typically permitted minor name corrections, such as fixing spelling errors, at no extra cost if reported within 24 hours of booking. However, substantial name changes or corrections beyond this window often incurred fees and were subject to their policies and fare rules. Passengers were advised to exercise caution during booking and review their details carefully. Please be aware that airline policies may change, so it's essential to visit the official Philippine Airlines website or contact their customer service for the most current information on Philippine Airlines name correction policy.
