Top tips for finding cheap flights to Vietnam

  • The San Diego International Airport (SAN) is a hub for Southwest, Alaska Airlines, and some regional airlines. When you book your ticket through KAYAK from SAN to Vietnam, you will have many choices of destination, airline, flight, and price.
  • If you are flying from SAN to Ho Chi Minh City, you will most likely be landing at the Tan Son Nhat International Airport (SGN). SGN is the busiest airport in Vietnam and serves as a hub for Vietnam Airlines, Bamboo Airways, VietJet Air, and others. Japan Airlines, American, and Alaska Airlines are among carriers that offer one-stop flights from SAN to SGN, with stops often in Tokyo.

Hostesses were very nice I am disappointed that I paid extra 900$for premium economy which wasn't much upgraded from regular economy, I have wasted my money on this trip 😫

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

Flight cancelled due to inclement weather yet rival airline EVA Air with the same route departed 2 hours later and landed safely while our flight was cancelled and rescheduled for 36 hours later.

The crew could have been kinder and less pushy. The premium economy seats don't have enough cushion. The seats are to hard and the flight became painful and uncomfortable after an hour of flying.

Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

I thought all the while when I booked my flight I am entitled to check- in 2 luggages of 23 Kg each only to find out that the ticket I purchased online entitle me for only one luggage. I have been traveling for over 20 years and this is the first experience to such… so frustrating.

I was pleasantly happy with this airline, which is new to me. The crew was attentive and the seats felt better than most other economy. There was plenty of bin space. Glad I got to pick the seat I had(based on distance from baby image on seat map).

The plane is very clean. The selection of movies is excellent!

They didn't tell me they changed my flight. So I got confused on what happened to my flight.

The flight was delightful overall. The check-in and boarding were on smooth and on time. Amenities and staffs were elevated. However, if glasses were served instead of cups, there should be a complete premium.

Sure I would’ve liked a little more space, but it was better than economy. I bring my own food because I have food allergies it would be nice if they offered larger salads or more vegetables instead of starch it was really a good flight. I don’t wanna complain. I’m grateful to fly at all safely. Thank you to the pilots.

American Airlines food is horrible. Also, paid to fly JAL on all segments, but received a much lower quality. I was disappointed to learn that we would be using American Airlines on this flight, which has less comfort, entertainment, choices, and lower standard of service. Overall not satisfied.

Food was very mediocre. Economy is pretty uncomfortable. Crew was excellent and responsive.

This was serviced by American Airlines. Not as great as Japan Airlines. The LAX domestic airport is not a great airport. We needed to take a shuttle to go to the gate. Mind you, this is just a connection, but we had to go to security again, which is a hassle after a very long flight from Japan. It makes sense, for our checked baggage to be picked up and moved to the other carousel for our final destination, but for us doing the security all over again, pointless. We had our boarding passes already when we were still in Japan, yet we had to start from zero again when we arrived LAX. There should at least be a different line for connecting passengers without going out like it’s our final destination. Next time, I will try to book our flights from any foreign countries non stop to my destination.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

Truly impressive service in the air. After the main meal, they have a delicious a la carte menu that you can order anytime until 1.5 hrs prior to landing. Flight crew were so pleasant and very efficient. Wish I could fly JAL more often!

It was an outstanding flight and service. The only thing is the seat cushion for economy could be a little more comfortable. More cushion.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

I thought I bought the ticket directly through Kayak not a 3rd party

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

I originally thought I was booking with ANA airlines and didn't see "operated by United" until the day of. I even thought the United check-in update was a scam so ended up checking in 3 hours before the flight, causing separate seating and uncomfortable middle seats.

Very disappointing. Our flight was delayed for almost 6 hours with the lost time disrupting our travel plans. United should have known that any delay (approximately and hour) triggered a no-fly/work because according to the FAA they had to many flight hours. After the mechanical delay (approximately an hour) we had to wait for a fresh crew change. Seems to me that United could have anticipated this incident. Again, a very disappointing travel experience.

There were 5 delays IN TOTAL there and back. And we got a $12 food voucher, RIDICULOUS. Will never fly Alaska again!

Orderly boarding; engaged, attentive and detailed flight crew. Late out of the gate but time recovered during flight; super landing and deplaning.

My flight was several times rescheduled and then finally canceled.

Short trip, was nice to have a drink on the short flight still.

Flight got delayed like 5 times, then they put and ada passenger in the back of the plane.

Flight delayed no communication. The gate was changed so many times.

Alaska is by far the best airline to fly with 😍

More efficient with checking lines and boarding/checking bags when needed.

They were really helpful with every question and my kids had never been on a plane and the staff made them feel comfortable

I was on flight #3022 departed from San Diego, California to Medford, Oregon. I had Denise & Damaris as my flight attendants. I didn’t have much interaction with Damaris, but I did with Denise who had, this calm, cool collective voice when she spoke about the emergency exit plans before takeoff. I travel often and I’ve never met a flight attendant that can put you at ease. I felt she respects and takes pride in her position and more airlines need to adopt the integrity and respect that she has for Alaska Airlines. Debbie

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The food was terrible this time. Otherwise pleasant, quiet, on-time.

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.
