I have always dreaded flying Philippine Airlines because the stories I heard from friends who used the carrier. Bangkok-Manila-Bangkok is around 3 hours flight. I chose Philippine Airlines because it's the only airline that uses Terminal 1 & 2 in the Philippines. Other international airlines are diverted to Terminal 3. The problem with Terminal 3 is that it's crowded plus there's a very very long walk from the Gates to the terminal, whilst Terminals 1 & 2 had a very short walk. My flight from Bangkok to Manila was a pleasant one, no flight delay, the meal was not excellent but it was OK, and the flight entertainment was functioning quite well (I was told some PAL airlines' entertainment were not working).
My flight back to Bangkok was a very horrible experience. All throughout the flight, the whole cabin smelled, especially when passengers used the lavatory. I was not able to finish my meal since I lost my appetite due to the bad smell. One certain passenger (seated at 59C) even made a mess after he used the facility, the worst part was he left the door open. While this was happening all the aircrew were behind the the cabin, most probably trying to avoid the foul smell. They only attended to the situation because we were about to descend so one of the airhostesses cleaned up the mess.
It was unfortunate that this happened and I hope Philippine Airlines will train it's cabin crew on how to handle such incident.
