Cebu Pacific is a low cost carrier, so you can not expect a lot.
Check in in denpasar, Bali , were smooth. Staff on board the a321 neo was friendly. The aircraft was new I think, I flew Cebu pacific before , and at that time seats would still recline a bit. These seats did not recline, but nevertheless I found them quite comfortable. They even have USB ports, so you can charge your phone. I was lucky that the 2 other seats next to me were empty, so I almost slept 3 hours.
The cabin was really clean. And most importantly, we arrived safe in Manila with over half an hour before sheduled arrival time.
