On Nov. 30, 2018 we have a flight from JFK NY ETD 1:45am to Manila, Philippines ETA 7:20am Saturday Dec. 1, 2018. Upon checking in at the PAL counter desk we showed our itinerary and our assigned seats 31C and 31B. Unfortunately, they said that those seats were already taken. We paid extra for this seats because we wanted the legroom. Why? They said there was a mistake. They offered us seats 32 which has no leg room. If we wanted a legroom seats there are 2 available in the premium economy but we have to pay extra $600.00 each. We don't have no choice but do it. This is not our fault and I demand refund of $1200.00 we paid extra. The seats at the premium economy is no different than 31C and 31B. Receipts for the $1200.00 is available upon request. I will take legal action about this matter and I will go public about this to our local TV station which helps problems like this from airlines.
