FAQs - booking Vietnam flights

  • Are there any direct flights from Portland to Vietnam?

    Given the long distance along this route, there are no direct flights available. The most direct flight you can find is on Alaska Airlines flying into Ho Chi Minh City via San Francisco. However, most flights will feature two stops, one in a US base and the other in a major international hub. Flights to Ho Chi Minh City in the south typically stop in San Francisco and Taipei or Hong Kong. Flights heading north to Hanoi usually stop in Seattle and Seoul before arriving in Vietnam.

  • Is a visa required for travel from Portland to Vietnam?

    Yes, U.S. citizens traveling to Vietnam need a valid visa, obtainable as an eVisa for durations up to 90 days, for single or multiple entries. Ensure your U.S. passport is valid for at least six months with two blank pages. The visa application and payment can be completed online, with processing usually taking between 3 to 7 business days.

  • What's the best airport to choose for a trip to Ha Long Bay?

    Ha Long Bay's impressive limestone cliffs are a must-visit destination. Hanoi is the closest major airport to the bay, and from here you can reach it by bus. However, if you prefer to fly into Van Don International Airport, we suggest choosing Tan Son Nhat International Airport as your arrival from Portland. Even though this airport is farther away, it offers the only direct flights into Ha Long.

  • How can I make the flight from Portland to Vietnam more environmentally friendly?

    Opting for a flight with fewer stops is the simplest way to reduce your carbon footprint while traveling. By selecting Korean Air for your journey, you enjoy the most direct route and contribute to their Green SkyPass Project. This initiative addresses environmental concerns by planting forests, aiming to achieve carbon neutrality.

  • How does KAYAK find such low prices on flights from Portland to Vietnam?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from Portland to Vietnam.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from Portland to Vietnam?

  • What is the Hacker Fare option on flights from Portland to Vietnam?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from Portland to Vietnam with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Portland to Vietnam?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from Portland to Vietnam up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Top tips for finding cheap flights to Vietnam

  • Your journey will start from Portland International Airport (PDX). To access the airport, the MAX Light Rail, located on the lower level, is a popular choice, with the Red Line offering a 38-minute ride to downtown. Alternative transportation options include taxicabs, ride-share services, and shuttles.
  • Vietnam features three main airports Noi Bai International Airport (HAN) in the north, centrally located Da Nang International Airport (DAD), and Tan Son Nhat International Airport (SGN) in the south. Select your arrival airport based on your travel plans and the primary destination for your trip.
  • With a flight lasting more than 20 hours, consider upgrading your ticket for enhanced comfort and convenience both during the flight and at the airport. Take advantage of Cathay Pacific's Upgrade Bid feature to name your preferred price for an upgrade to the next class.
  • On Korean Airlines flights, passengers can enjoy traditional Korean dishes like bibimbap or dotori, alongside popular Vietnamese favorites. The airline also provides a variety of special meals tailored to accommodate dietary needs, allergies, or religious restrictions.
  • Passengers flying with Alaska Airlines who have cognitive or developmental disabilities can find support with their Fly for All app. This takes the anxiety out of flying by walking them through the necessary steps and giving them an alternative way to communicate.

Everything is smooth. Very good. Except flight arrived SFO 30min late.

more new movies and the blockbuster movies that everyone likes

Great airline. Kind staff, before m, during, and after the flight. They Directed you the whole way. Even when I arrived at my transfer destination, flight attendants guided passengers on which direction to go. I would definitely fly STARLUX again.

Got dinner and breakfast! They had mahjong game in entertainment system. Current movies. Loved the slippers, sleeping mask packet. Great experience for a long flight

Leg room was great. Friendly crew. Food is great. Crew always kept the toilet clean.

Excellent. Airline was very clean, staff was excellent, very professional. Economy seats were still large and comfortable. Meals were included and with good options. We were given a blanket and pillow as well as a comfort kit including an eye mask, ear plugs, and tooth brush. Would highly recommend.

Business Class is exceptional, from the lie flat seats to the wide range of food on board. Can’t wait for our next journey with Starlux!

Th tray was dirty when pulled it out. Still oily and food stains can clearly see last trip cleaner did not clean well. The toilet sink water did not drain quickly enough.

Majority of the movie entertainment loaded in the aircraft were quite old.

Crew is very attentive. Another new airbus 350-900 plane. Very modern.

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.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Everything was fine except the seats were quite compressed and hard for the 12 hour flight

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

Flight attendants. Food, entertainment and most of all, be on time.

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

This was our fourth domestic flight with Vietnam Airlines, and once again we found the experience very suitable. Check-in was easy and efficient. They did take our carry-on luggage, but that was fine. I’m actually happy not to deal with it on such a short flight. The flight was just over an hour, departed on time, and we climbed above the clouds into a beautiful sunset. Even on such a short flight, they served water, which we appreciated. Luggage came out into carousel in Nha Trang in good time and off we went to meet our GRAB. Also, Vietnam Airlines have easy to locate ground level offices in cities and towns where you can get assistance with staff. I liked this service as we did go visit one in Nha Trang. We would definitely recommend Vietnam Airlines and wouldn’t hesitate to fly with them again.

Really good 👍 This was our first time flying with Vietnam Airlines. It was a short domestic flight, so no meal service, but boarding was organized and the flight departed and arrived on schedule. The flight attendants were professional and neatly presented. All in all, a very good first experience. We would recommend Vietnam Airlines.

We flew with their partner VESCO on a small plane, it was a really good flight. There was no food or entertainment as it’s a one hour hopper flight.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

This is a very short commuter flight, so there is no food or flight entertainment. Hence, I marked it in the neutral flight left on time. The plane was full pretty much and it was a pretty easy flight overall very good.

The flight crew and attendants are very professional and polite.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

They promise free wi-fi prior to boarding and then once on board you are informed you have to purchase wifi even after being a mileagePlus member.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

Awful. No counter attendants. No dinner offered due to delays.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Flights were on time. Free Wifi on plane. Everything was well organized.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.
