reach the standard, crew tried to fix up issues fast.

The flight was fantastic and the crew was absolutely excellent, but the entertainment system on the B777 was not working. That's a long time to spend with no electronics. The crew offered I-Pads but I had brought my own. I am only pointing this out because this is the second flight on Philippines Air where the entertainment system was down. FJM

Theairline, both at the terminal and during the entirety of the flight were kept at uncomfortably cold temps. Maybe between 55 and 60 f. Those who had traveled with the airline before donned puffer jackets, wool hats and pulled blankets from their carry-on bags. The seat back entertainment also failed on my trip, leaving me for 12 hrs. With nothing. Seats offered enough room (barely) for a 6'1" frame, but it was pretty tight But the worst offender was the uncomfortable temp..

The checking in agent tried to give me a different seat. She tried to give me an economy seat even though I had already checked in with a seat assigned and paid an extra $300 for those seats. She also separated our seating assignment. Very unprofessional and seriously a bad example for an agent. She was rude when I showed her my receipts and she made us wait more than 15 minutes before we were able to get the right boarding passes and correct seats (seats that we paid for in advance)!!!

Purchased exit row window seat for extra leg room and sleep. Worth the price. Attendants maintained restrooms regularly. No snacks/chips/nuts/cookies beyond what was served with meals.

Delayed, from morning flight, they moved to evening. And said, their earlier flight is already full but we can upgrade the seat

Not so good, my business seat is not working properly

Nice new lay-flat seats in Business Class!! What a wonderful experience!

Well it's strange everytime going the flight is late coming back the service is superior

Going to Dumaguette 4 times in a row I was late it's terrible
