Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Flight was good but there are way to many announcements for credit cards etc.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

Plane are getting old, almost an hour delay due to technical reson , after all passenger aboard. Took 4 flight on business class this trip and all the planes had an issues. PAL need to improve their planes.

Food could of been better. Crew was pretty much average. It was raining a lot on arrival, had to take a bus to immigration building,

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

Crew excellent calling me by name ! Only downside was no inflight WiFi

I was glad that the plane was not totally full.

Everything was very good but seats are small for a big man!

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

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.
