- The check-in counters opened at least 30 minutes late. The agents arrived late, they seemed to be having a good time and didn't feel the need to explain the reason for the delay nor apologize for it. - On my flight to Manila from Los Angeles, I did not check in any luggage. I had a carry-on and a backpack that fit perfectly well into the overhead bins and underneath the front seat. On my flight from Manila to Los Angeles, I was not allowed to take the same set on board because the total weight exceeded 7 kg. This put me in a bind because the heaviest item I had was my small LCD monitor which was in my backpack. I had to put it into the carry-on with wheels which I had to be checked-in. I would have prepared to carry it in my backpack because it is a fragile item. When I was told to sign a document that absolves the carrier of any liability for the checked-in luggage and I refused, the China Airlines Duty Officer in Manila informed me that unless I sign the document, my luggage will not be loaded on the plane. I felt extremely frustrated by the attitude of the Duty Officer who didn't hesitate to threaten me and insisted that the rule was imposed on them by the TSA in the US. Instead of helping me work out a solution to the difficulty I was facing, he simply walked away with a dismissive attitude.

The flight was so crammed. I understand there's the possibility of flying on a fully booked flight but if it took an hour to load the passengers how quickly can you realistically get 400 passengers out? Plus it prevents everyone from having an overhead cubby. You need to reconfigure the flying experiwnce.

Going back home to the US

I had 15 hours layover in Amsterdam so I got me a hotel.one hour after I got to the hotel I got a notification from Kayak app asking me to go get my bag from Schiphol. My bag was supposed to be directly shipped to PDX. I had to leave my hotel back to the airport and spend 2 hours trying to find it only to be told that it was going to PDX. I lost my $170 hotel room, over $70 for taxis and ended up spending the night on the floor at Schipol. I do not think I'll ever use Kayak again. The travel guarantee is a joke too.

Ease of boarding and good communication from pilot

Flight attendant was gruff when communicating. She seemed angry when providing information. It was a short flight, so not a lot was offered, which was totally fine. However, when she walked down the isle with water, she appeared to be looking at the ceiling and didn’t stop to check if many people wanted water, including me.

The food was tasty, as usual. The crew were attentive and it was a relatively smooth ride.

The boarding gate was located much further than I remember for previous flights. And then we had to board shuttle buses to the plane, which made for an unpleasant boarding experience. Too many carry-on bags onboard meant no space for my bag in my allocated overhead bin. The plane seemed old and the seats were small and cramped. The entertainment systems kept shutting off in the beginning of the flight, and my screen was slightly unresponsive to touch. Not the best flight experience compared with what I'm used to and expect from Turkish.
