JasonFlew with ZIPAIR-Aug 2026

You don't need the meal, eat at Tokyo and relax on the flight. Bring water & chargers.

AnshumanFlew with Japan Airlines-Aug 2026

Make sure you carry your own food if you are vegetarian

Verified travelerFlew with China Eastern-Apr 2026

Choose a evening flight if you are flying business, so that you could sleep while flying. If you are leaving PVG around noon time, it would be difficult to fall to sleep.

NoelFlew with Cathay Pacific-Mar 2026

Baggage handilng make sure to report any issues, like lost or damage immidiately, even if you miss your connecting flight , they will reschedule you, but if you have a fixed schedule, report as soon as possible , happend to my recent flight march 24,2026

KaushalendraFlew with American Airlines-Apr 2026

Don’t book via third party apps for Cathay Pacific flights, they don’t recognize the itinerary and won’t be able to even view details like airport terminals or gate numbers

Verified travelerFlew with Air China-Mar 2026

Only tip, eat before boarding the plane, Airline food, not just Air China, has become worse over time. Air China's food was better prior to the pandemic.

Verified travelerFlew with EVA Air-Jan 2026

It is a long flight so be prepared some book to read, play sudoko to relax mind or bring your own soothing blanket or neck rest to sleep on the plane. Do not forget to ask for ear plugs to block the noise if you needed.

Verified travelerFlew with Japan Airlines-Jan 2026

Don't get to the gate too much earlier than you need to, it is very easy and fast to get from baggage drop off through security and to the gate.

Verified travelerFlew with EVA Air-Jan 2026

Going through immigration services is pretty quick. The agents were nice and efficient. But there is not distinct direction for foreign vs US passport. There should be someone there direction traffic. Don’t be afraid to ask. That is why they are there. My last visit, everyone just picked a side and guessed. There was a mix of both and we all got through. So I don’t think it’s as big a deal in SF that it is in other places. You all end up at the same baggage claim anyways.

Verified travelerFlew with United Airlines-Feb 2026

Prepare to bring your own food & snacks on board to eat, food on plane sucks, very cold on plane

DrewFlew with Philippine Airlines-Jun 2025

Pack a hoodie and wear pants. Don't purchase anything past initial security check- youll have to empty any drink- even a sealed cola can- before getting through a secondary screening at your gate.

Verified travelerFlew with ANA-May 2025

Bring your own meals like sandwich, nuts, fruit, or protein bar, because the food not only smells fowl but tastes even more so. Jesus, I’d rather just eat a protein bar.

RamFlew with United Airlines-Feb 2025

Fly United. Give yourself a lot of time to get to the gate

Verified travelerFlew with United Airlines-Dec 2024

Book flight paths with only 2 flights rather than 3

Verified travelerFlew with United Airlines-Dec 2024

be careful of short connection time when reaching US.

Verified travelerFlew with Japan Airlines-Dec 2024

Get to the airport early because ground transportation to/from takes time and patience. Horribly crowded airport takes time to understand if one doesn’t understand Japanese language. Transfer time from previous flight was obviously not long enough and yet this was what booking service recommended

Verified travelerFlew with Japan Airlines-Nov 2024

This trip seemed shorter than I thought. Sleeping helps pass the time. Also take an aspirin and wear compression socks

Verified travelerFlew with United Airlines-Oct 2024

Procedures in Tokyo Narita airport are very efficient. Transportation to and from Tokyo is also efficient, economical, and available.

Verified travelerFlew with Japan Airlines-Oct 2024

Get a butt pillow for the long flight and a neck pillow to sleep comfortably

Verified travelerFlew with Cathay Pacific-Sep 2024

Get there earlier if you are a transit passenger, there are stores and restaurants but we flew in almost midnight and most stores were closed. Be your own advocate and look around what other passengers are doing!

Verified travelerFlew with United Airlines-Sep 2024

Double check your boarding information in airport in time, like boarding gate, or boarding time, etc. because they might be updated.

JohnjimyFlew with ANA-Aug 2024

If you have multiple carry-on. You may be subjected to have tags or have to pay, due to limited spaces. I was fortunate to have my bag under seat for take off. Other passengers decided to bring the whole room with them without me having space to put my backpack carry on.

Verified travelerFlew with China Southern-Jun 2024

Monitor flight information closely in case unexpected cancelation. Other than that, everything was good.

Verified travelerFlew with United Airlines-Mar 2024

I have not flown other flights to Tokyo, so I have not much to add here. I did appreciate the option of a direct flight to your destination. Having to connect to another flight is at minimum a 2 hour add to your traveling time to an already long flight. Even though a connecting flight you have been more economical, the saved time will s worth the slightly extra cost to me.

RickFlew with United Airlines-May 2024

Haneda Airport was most convenient for me. My friend lives in Chiba so Haneda was closer to drop me off. There was a monorail if coming by train, so that came be convenient too. Check in was a breeze and also ANA accepts luggage forwarding service from our hotel which made it more convenient too!

Verified travelerFlew with ANA-May 2024

Haneda airport now handles most of the international traffic. It's much closer to downtown Tokyo. Narita is 45-55 minutes out of town. Do online and complete you immigration documentation before your flight. Print the QR code and the machine will scan it along with your passport. Much faster.

GordonFlew with United Airlines-Apr 2024

Check your all or most of your luggage if you can. Take a small light carry for your must have items with you such as snacks, book and electronics on hand accessible during the flight.

Verified travelerFlew with Air India-Mar 2024

Don’t choose Air India. Immigration and security checks in Delhi was very crowded, took almost an hour and half to go through. Need plenty of time to transfer from domestic to international.

SoukindaFlew with Singapore Airlines-Feb 2024

Bring a sweater, a mask and wear socks. Although they provided a blanket, it’s very chilly on a long flight. I caught a nasty cold from the flight and wasn’t masked up. Other than that our flight was great and comfortable.

SoukindaFlew with Singapore Airlines-Feb 2024

If you are flying with an elderly parent that needs to be near restroom, have an agent place you in the back. They will take care of you.

ManishFlew with Air India-Jan 2024

Qatar and Emirates are so far best options. Landing in domestic airport had pain of taking baggage from baggage claim and then again be in line to checkin the hand bag even though bag was tagged to final destination. So we have to avoid flights landing in domestic airport during transfer with layover.

MITESHFlew with Air India-Jan 2024

Don’t go with any regular expectations. This is point a to point b. Put on your noise cancelling headphones, bring your own food, close your eyes and go. This is still the most efficient flight travel time wise.

amarjitFlew with Air India-Jan 2024

I would like to suggest before leaving your home, keep some medicine with you.
