Flights from Osaka to California: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Osaka to California 
Verified travelerFlew with Japan Airlines-Jul 2026
If traveling JA bring your own seat padding like a sweater or blanket. Customs and security in Osaka was super fast with facial recognition so you don’t need to arrive to airport super early but if you do they basically have a mall in tbe terminal to keep you busy for hours and spend any left over Yen
Verified travelerFlew with Japan Airlines-Jun 2026
Japan Airlines is a difficult airline to check-in on both the app and on-line. It is best to to call and have them walk you through their process. Know that they have limited hours for customer service and may be open only Monday - Friday. Highly suggest that you visit Visit Japan Website and Register for Immigration and Customs.

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

My flight was amazing smooth and the attendants were so friendly and nice

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

More seat space More bathrooms Charging outlets Plane was old

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Great service and comfort level. You can have more of vegetarian food options.

I took several flights that day, this was the only flight that was absolutely freezing!! It was so cold.

It was a comfortable flight and the flight crew were lovely!

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

They destroyed my Michael Kors Carryon luggage, they didn’t announce that only check in the carry on and when we get inside a couple of room to put the carry on bag. I was disappointed and sad because of the damaged of my luggage. They should replace it or fixed it.

The airplane very small , no space for put my carry on , they tell me loads my carry on I thought they will load my carry only Seattle to San Francisco but when I get off airplane at San Francisco they just tell me load my bags from Seattle to Bangkok Why they don’t tell me before load . I told them I don’t want load my bag from Seattle to Bangkok , because my carry on had medicine. Why crew from Seattle don’t help me , they only told my go to tell luggage claim Delta

Food was not great. Crew was lovely. There was no whisky on the first leg (BKK - ICN). And it took forever for my luggage to come out at LAX.

They let me board first because I'm a cancer patient & 75 years old. That was greatly helpful.

Good. The only thing is that I missed the flight.

My seat was so hard and uncomfortable. I took AA to Japan longer flight no tailbone pain. Coming back on JA shorter flight my tailbone was killing me no cushion on seat or just worn out.

It was amazing. Japan is lovely. I hope to go again. Thank you for everything.

I have been flying with JAL a few times, crews service, food, overall comfort even with economy, I would rate it the top three airlines. None of any American carriers can provide such excellent service.

I really love their services! From checking-in to deplaning, superb! Highly recommended!

I love Japan Airlines! I go out of my way to book with them. It is regrettable that the One World Alliance includes American Airlines though. The last leg of my flight from LAX to Austin was easily the worst, most disorganized part of the trip. Next time I will plan to fly directly from DFW to Haneda to avoid American Airlines as much as possible.

My total experience was good. The food and entertainment need improvement.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

Great service but food taste and options have gone down a few notches.

Very comfortable unlike my first trip where they switched my flight from JAL to AA which was a disaster!

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

Coming back to America was a peaceful flight everyone and everything was perfect

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Everything is good, the only issue is the aircraft need to be upgraded

The legroom in economy was better than other airlines. Since my legs are long, that means a lot. Also, the A380 from Los Angeles to Incheon gave passengers a smooth ride. Everything went smoothly from boarding to disembarkation in Incheon. I'd fly Asiana again!

The flight attendant, where kind of rude, there where hiding for almost 3 hours, without doing rounds to see if people needed water or pickup the water cups, the toilets were full of water cups, because they never come back to pick them up.

Amazing service and fabulous syaff. Loved the jumbo jet too, comfortable.

My experience with Air Canada flight was really good. The seats were comfortable with decent legroom, and the staff was very polite and helpful throughout the journey. The food was tasty and served on time, and there were plenty of entertainment options which made the long flight feel much shorter. The flight was on time and the landing was smooth. Overall, it was a comfortable and stress-free journey, and I would definitely love to travel with Air Canada again.

The boarding process was going smoothly until the manager Bharti Singh insisted I check my duffle bag that fits under my seat. I travel with the duffle for this very reason. I know for a fact it fits under the seat. She was rude and aggressive, I was charged a check bag fee. She reminded me that I purchased a “basic”ticket. I fly Air Canada more then ten times a year and have spent thousands of dollars on tickets with Air Canada. Once the boarding closed there were many empty overhead bins. The airplane was an old, with no entertainment. The flight attendants were not pleasant, no smiles, not even friendly with each other. Over-all, seemed miserable. I fly all the time and have never experienced a flight crew so unpleasant. This was the worst flight I’ve ever had. If I didn’t have to fly Air Canada I would not use them again.

flight was full and no chance of getting a better sit. other than that. it was ok.

It was a good flight and we arrived on time, plane was clean.

Not to out myself as both a child at heart and kind of a terrible person, but the Pokémon safety video was the first time I watched an airplane safety video in like a decade. It was ADORABLE!! A great way to encourage attention from young and old alike.

I’m writing to share my deep frustration with a recent experience, which I feel reflects a troubling trend in the airline industry—one where customer care often takes a backseat to profit maximization. First, I do want to acknowledge a positive aspect: I appreciated that your team accommodated a seat change due to my medical needs without charging an additional fee. This gesture made a genuine difference during my trip, and I’m thankful for that. That said, the overall experience left me extremely disappointed. The ticket I purchased for myself and a companion turned out to be “basic”—a fare category I now understand to be non-refundable and non-transferable. Unfortunately, my travel companion was involved in a car accident and could not fly. Not only was I unable to receive any kind of reimbursement, but I also couldn't transfer the ticket to someone else, despite the flight being overbooked by three passengers. This inflexibility felt exploitative. To add to the frustration, I had to shoulder additional unexpected expenses: overpriced in-flight food and a costly baggage fee on my return trip. The entire process felt more like a profit-maximizing scheme than a customer service experience. I understand that airlines, like any business, need to remain financially viable. However, creating fare structures that penalize customers during emergencies, while simultaneously overbooking flights, comes across as deeply unfair. It’s hard to feel like a valued passenger in this environment. While I don’t expect much will come of this message, I do hope Air Canada takes this feedback seriously. There’s an opportunity to lead with integrity in an industry where choices for consumers are becoming more limited and experiences increasingly transactional.

Still haven’t made it home. Delayed twice, then cancelled. Will never fly Air Canada again. Horrible experience.

First time flying with Air Canada and very impressed! We will definitely book with them for future trips.

Very comfortable flight, despite being in the middle section, in the middle seat! Airline staff was very accommodating. Food was good and we just became aware of the meal options. When we flew from Toronto to Osaka, we were offered 2 meat dishes. We are pescatarian. The flight attendant went out of her way to bring us food we could eat. We look forward to flying with Air Canada in the future!

THE AIR CANADA CREW NEEDS TO MORE PROFESSIONAL AND COURTEOUS. UPON TIME OF BOARDING, THERE WAS A SPECIFIC AIR CANADA STAFF WHO WAS EXTEMELY RUDE. WE WAITED ON THE SIDE TO WAIT TO BOARD. SHE AGGRESSIVELY PUSHED ONE OF OUR FAMILY MEMBERS ON THE ARM TO SIT WHEN EVERYONE WAS STANDING BY TO BOARD. THEY WERE EXTREMELY UNORGANIZED. EVEN AFTER BOARDING, ONE OF THE STEWARDESS WAS TRYING TO CLOSE THE OVERHEAD LUGGAGE BINS AND I WAS SURPRISED WHEN SHE PUSHED THE PASSENGER'S LEG WITHOUT SAYING "EXCUSE ME". THE STAFF AT AIR CANADA TRULY NEEDS TO LEARN THEIR BOUNDARIES. REGARDING PHYSICAL CONTACT. SUCH BEHAVIOR IS INAPPROPRIATE. AIR CANADA HAS BEEN THE ABSOLUTE WORST EXPERIENCE!!!
