Check in early to get a good seat assignment
Verified travelerFlew with Asiana Airlines-Jun 2025
Do not check a suitcase take a carry on
Verified travelerFlew with Jin Air-Mar 2025
Arrive early, No automatic baggage sending - all done manually
MariaFlew with Asiana Airlines-Dec 2024
If you're flying into Ho Chi Minh with a different airline, make sure you have printed tickets because security does not accept mobile tickets (only printed) and hopefully other airlines are better than Asiana otherwise, plan to spend several hours in the transfer area with nothing available other than bathrooms.
Verified travelerFlew with Hawaiian Airlines-Sep 2024
I will not fly to ICN and transfer to Hawaiian again. Both Asiana and KAL are good flights to ICN. And their lounges are both good. But if flying onward, stay with Asiana or KAL connections. ICN doesn’t do terminal connections well.
ArthurFlew with Delta-Jul 2024
Make sure to select an aisle seat. Korean Aur flight attendants are. very nice and try to help . My overhearing light was broken !
Verified travelerFlew with Cebu Pacific-Apr 2024
Do not take a budget airline next time. If there is no choice but Cebu Pacific, then don't pay for checked bags. Just bring a huge backpack, a carry-on suitcase, and one big handbag (personal item) up to 10 kilos each. Cebu Pacific does not care about these things anyway.

The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

Excellent. All well and accommodating. Clean and very good food. Peaceful travel experience

The food wasn't to good but the crews were great, clean plan clean bathrooms always

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

I upgraded my flight to business and before boarding they told me they will not have food on the flight unless someone declines the food service.

Boarding on any airline is a hot mess. Load your pivilaged passengers, then back to front. Back to front.

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

It as great, my in flight entertainment was malfunctioning though.

The flight was delayed for half an hour, hope this can be better

Average flight for which I paid too much for on a last minute purchase.

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Absolutely terrible. I will never fly that airline again. The problem was with the constant emails changing my seats, arrival/ departure times and the aircraft. The staff at the airports and onboard were great. Between making the appointment in May 2025 and my actual trip I had over 50 emails announcing changes. I was traveling with 3 other couples and they experienced the same thing.

I was glad that the plane was not totally full.

Well, I needed to make a change to my flight and I called the airline and they said yes no problem $700 and we can do that and I agreed to it so they canceled my tickets and went to rebook and came back after being on hold for an hour and a half and said I’m sorry, sir. There was an error. It is $2800 Now and I said never mind. I will just use those flights and she proceeded to tell me that they already canceled them because I said I was interested in doing the change. I told her yes for $700. I was fine with doing a change but not $2800 so give me my tickets back and she proceeded to tell me that she could not do that and I had to pay the $2800 to get my tickets back that I already spent $2800 on. So I had to book tickets on another airline to get home And that cost a lot of money too. I’m a little pissed off at Philippine airline right now because of what they did to me and I’m not sure I ever wanna fly with them again. I’ve flown with them plenty in the past, but this just really put a bad taste in my mouth.. Not to mention on my way there leaving Seattle going to Vancouver. I got to the airport three hours in advance and they had booked me through Alaska Airlines to do that little trip. My connecting flight would leave about six hours after I got to Vancouver BC. I stood in Alaska Airlines lying for a little over two hours and then they proceeded to tell me that they couldn’t check me in because I wasn’t there an hour in advance. I kept telling the lady at the beginning of the line that I was afraid they were not gonna let me in because it was taking so long and she said oh don’t worry about it. You’re fine you’ve got time. Well I ended up spending $600 to get to Canada that night just to make my connecting flight because Alaska air wouldn’t do anything and Filipino Air told me it was Alaska air problem but Alaska air said since you booked through Philippine air, we can’t fix it. I had about 50 minutes to make my flight, but they refused to check me in because I wasn’t there an hour in advance yet. I’ve been standing in their line for about two hours and 15 minutes.

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

Great ride! arrived safe and sound. Everything was great altho its still uncomfortable seats too small space to pass through in.

everything was excellent the crew the food, crew was extremely friendly but wish there was a tv..📺

Biz class is way below what other airlines offer. The food was mediocre at best. A WiFi was intermittent and movies were dated. Honestly the best part of the trip was that the Mabuhay lounge in SFO was closed and they gave us pass to Air France lounge. My advise, fill up there before boarding plane.

No power on an 11 hour flight? What a joke. Crew did not come by enough to get trash or offer water.

Checking in was okay but boarding a little bit slow

When on flight the crew was great. The checkin was also great. What Philippine Airlines need to improve is the boarding process and being on time it is bad when the times I have flown with them they are always late which costs me more do to additional parking fees missed connections.

Your check in lines were terrible everything else was great!

It arrived 18 minutes early. Attendant are good. For baording , they should improve especially carrying thru bus.

Boarding had us in a tunnel with no AC for 15 minutes. Not planned well. And you have to pay for water, get at airport

Bags lost for the second time. Will not fly with Cebu Pacific again.

Delays on the tarmac, uncomfortable even after paying extra for premium seats. Bags lost in transit, no compensation provided

The seats are too cramped, there is barely enough room to shift weight. This could be easy to endure in a one-hour flight, but not more than that. The crew did not clean up shortly after meals. The tray table remained open because of the meal and ate up what is left of the little seating space. The crew were just idling by for 45 minutes before they collected the trash. The airline did not inspect carry-on luggage. Most of the passengers brought too many bags, too large and/or over the weight limit. This undermines safety and discourages those who pay extra for checked bags just to comply with the airline regulations. If the airline is not inspecting carry-on luggage, why should I pay more just to check in some bags?

better handling of the checked in luggage. they destroyed mine

Crew was very helpful because I used a wheelchair to get around

Flight was delayed for almost 30 minutea, I had difficulties to catch up the connecting flight. Bit due to tje well organized Singapore airport I was able to make it

Flight was 2 hours delayed. No explanation provided. Gates changes twice.
