Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX. Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

The seats are too small for international flights. I felt like cattle.

As my first experience in business class it was a great trip considering how long the flight is and how hard it usually is to sleep in economy

Crew was professional. Never enough leg room for 12 hour overnight flight.

Fast boarding. Cabin temperature was a bit warm, but I guess this is the standard in ANA. The Room seats are spacious, but not long enough for me.

ANA crews are superb, very responsive and caring. Boarding was smooth and so as the landing. Great flights we had with ANA.

Great service, wonderful meals, excellent entertainment, clean bathrooms, top notch experience

The cabin temperature is warmer than I expected and there’s no other way for me to control the temperature. It’s centrally controlled so it’s consistent for everybody. There’s no air flow that I could direct to me if I’m hot. I also noticed people wearing sleeveless shirt. I’m not the only one who noticed that the temp is warm. In a crowded plane, temp should be a little colder, not warm. People can use sweater or use blankets. When it’s warm, there’s no other way to cool down. All 3 ANA planes that I’ve had this trip were all the same. It’s warm. It gets a little claustrophobic if there’s no air flowing or the temp is warm

ANA was wonderful just needed to upgrade the food and the entertainment.

bag dropped took over an hour. there was only one agent behind the counter. Definitely need improvements on food! crews were very pleasant n helpful

The self-baggage at Narita provided by JAL only worked for half my baggage, but the staff present at the counter were very quick to provide assistance. When I arrived in Vancouver, after waiting for ~25 minutes at the baggage carousel, a staff member with a JAL badge quite rudely came up and told me that there was no more baggage coming to the carousel, and I should double check that the baggage that wasn't mine, just in-case my baggage had somehow changed into a different one. After ~3-5 minutes more baggage came out onto the carousel, which included mine.

everything was great except for the plane itself looking worn out.

It was great, but the wifi service was very hard to pay and I barely could use it during my trip. The seats are also a bit tough for tall people (economy area). Other than that, it was a pleasant experience.

The airline was very clean, and the crew very kind and thoughtful.

Service is excellent - crew all so respectful and friendly. Airline comfortable - lots of legroom even in economy. Food was great even came with ice cream!

Just a little puddle jumper from Los Angeles to Vegas. Not much can be said, I had to go ask for some water.

WiFi inflight was not working. Then they told everyone they had no beef for the steak option. So that left just sea food and snacks. So all I ate for the 11 hour flight, was an ice cream sundae. Gave out Casper mattress pads, which are always so nice.

Management of serious allergens despite advance notice. Did not know ingredients contained in their own food. Went as far as to have parents try to ‘take a look at the food’ to ‘see if it was Ok’ since they did not know ingredients. Will inevitably have a passenger with a severe incident if they do not train better.

Great service. Premium coach seat was uncomfortable. Food was non-descript.

There is issue with first name and every thing is correct, and they did not onboard, it was really bad experience I recommend not to buy ticket and support team is very poor ever though online support is very bad

Plane is very old and not the same seating as online No per seat entertainment The large shared tv wasn’t working Didn’t provide headphones No announcements of departures or arrival from captain or crew

The staff were courteous. The best part is that this airlines has a place designated for prayer. As a Muslim it’s very important for me to be able to pray and the airlines facilitated this for me and others who were on the flight. The other great aspect of this travel is there was no alcohol served. I love this airlines

The entertainment system on my seat didn’t work for the whole length of the flight, staff was not helpful. Horrible experience. Its so hard to go through a flight from LA to jeddah with no movies.

Very friendly and efficient staff. Would definitely fly Saudia again.

Entertainment on all 4 business class seats were terrible audio and could barley hear. The 11 hour layover in Riyadh was a nightmare and no one told us that nightmare matter what we do or what we were willing to pay there were no places to rest or sleep and nine of the lounges allow you to enter them no matter what unless you are 4 hours or less from flight time. With a 78 yearold mother with me this is ridiculous. The employees of the airline in Riyadh and of the lounge treated us like servants or lower class people. Never again

I wonder why checking carry on bags while the checking process was done by Moroccan security. Is it question of trust or Morocco security system is not qualified enough?

J’ai mon carte de fidélité Sky team gold À Dubaï je me sui présenté avec mon carte je sui rentré dans le louange Maintenant arrivé à Riyadh on m’a refusé que je rentre que parce que c’est la carte de Air France Et pourtant il y’a le partenariat bon brefs Tout ça c’est du racisme parce que je suis un africain

Food could be better. Bread should be warm served with butter. Bread quality is bad and cold served.

Entertainment for non Arabic speakers is very limited. Seats were comfortable. Seat map while booking showed 2-2-2 config, but the flight had 1-2-1..

Left late after one day delay. Even after we were called to board we stood in line for 30 minutes. Seemed disorganized.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Luggage management is poor, my missing luggage is still lingering.

Short and everyone communicated with me about the changes every step of the way.

Crew was good. Check-in and boarding was terrible. Family wasn’t seated together. Online check-in wasn’t available.

Airline staff was good the checkin process was ok but the plane itself was very bad the comfort was worst it was worst and the most stiff 5 hours of my life i felt claustrophobic

Flight got canceled after a 2 hr delay followed by the to crew timing out. No help with hotels, crew were rude, only help was via an online chat. Got rebooked for a non-direct flight 48hrs later. They could not have cared less regarding how this could create a medical emergency. They refused to give us access to our luggage because it was stuck in their transit area and had to remain their to be loaded on our next flight…so we have the clothes we have in and nothing else. They told us to “go buy clothes” ignoring the fact that Munich shops are all closed on Sunday. We were told we could get refunded for our expenses BUT one crew member told us it would be wise to spend as little as possible as it will “take forever to get your money returned”. I’ll never fly them again.

We left 3 hours late. Of 4 flights on my trip, 3 left at least 3 hours late and one flight was canceled

Brutal as can be … delayed by 24 hours then delayed and hour on the tarmac then delayed three hours in Chicago, screaming child behind me kicking the seat for the better part of 10 hours… couldn’t be worse

Not much legroom in economy seats and aisle. Bathrooms are not maintained well. Staff can be friendlier. Food is barely edible.

Flight was delayed and caused us to miss our connection. American Airlines did nothing to compensate us and they lost 2 out of 4 of our checked baggage. They have not returned inquiries into customer service and have not offered us compensation. Terrible.

The PAL employee who assisted my minor children went above and beyond her job and our expectations! Sophia was kind, courteous and made sure my children were taken care of!

Service was good but food needs maybe it’s just me Cause I am a foodservice supervisor more menu Sampling to get better quality when packed to be reheated . Vegetables are already dark and over cooked and breaded entrees are not the best choice I guess . All airlines meal service doesn’t appeal To me.Cause this trip I’ve used 4 different airlines and nothing good in all of them food wise. Thanks

Overall it’s very acceptable I will gave an A.

Food was satisfactory, movie monitor not working. Other than that on time and pleasant crew.

They were two hours late!! Threw everything else planned off.

Flight was cancelled and rescheduled to 205 in the morning at the peril of passengers. No hotels provided by the airline. Passengers left stranded at airport. Not acceptable. I was able to get a hotel at my own cost outside of the airport. No reimbursement. Won’t be my choice in for future travels.

Worst airline. They had 3 security checks just to get onboard and no notification prior. Had to throw away any liquid bought at duty free because one of the security checks was prior to boarding the plane. My onboard media console was not working, the flight attendant said they will check on it but did nothing. Pretended we did not ask for it to be rectified for a 17hr plane ride. Horrible experience. My first and last time taking Philippines Airlines.

Uncomfortable seats for international flights. No usb charging yet they want you to use your device for entertainment. Very poor.
