FAQs - booking Thailand flights

  • If I have booked my ticket to fly from San Francisco to Thailand, what type of visa will I need to get before I travel and will I need a passport to travel to Thailand?

    For those travelers that are making the trip from San Francisco to Thailand, you will need a valid passport. The passport in question needs to be valid for at least six months from your date of entry into Thailand. Make sure that your passport has at least one blank page for entry immigration stamps. If you are traveling as a tourist and you will not be staying in Thailand for more than 30 days, you will not need a visa to travel there.

  • If I have made plans to fly to Bangkok Suvarnabhumi Airport (BKK) from San Francisco, what type of public transportation should I expect when I land at the airport?

    One of the most convenient and cheapest ways to get from the airport to downtown Bangkok is aboard the Airport Rail Link City Line. This train makes the trip between the airport and downtown in around 26min and will set you back about 49 THB (1.50 USD).

  • If I'm going to be driving with my children in the car in Thailand, what are the car seat laws there?

    It might come as a surprise to visitors from the United States that Thailand does not have any child seat laws to speak of. With that in mind, it is probably best that you bring along your own child car seats on your trip as they may be hard to find once you arrive in Thailand.

  • If my plan is to visit the Phi Phi Islands when I travel to Thailand, what is the best way for me to get there from San Francisco?

    The quickest way to get there is to travel on one of the many one-stop flights available from San Francisco to Phuket City Airport (HKT). Once you arrive at the airport, you can take a combination of buses and taxis to get to the ferry service port to take a ferry to the islands. The trip from the airport to your final destination will take around 2h and it will cost about 1147 THB (35 USD).

  • How does KAYAK find such low prices on flights from San Francisco to Thailand?

    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 San Francisco to Thailand.

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly from San Francisco to Thailand 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 San Francisco to Thailand?

    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 San Francisco to Thailand up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Premium Economy seats were more comfortable than other airlines I have recently been on. Great staff. Food was unremarkable.

The crew very accommodating and food too is good. Keep up the good work

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

Overall the flight was what might be expected for a long haul flight to Asia in economy class. The cabin crew was attentive and the food was good. Boarding was fairly fast and easy. The one thing I found frustrating was the EVA app. It is terrible. Trying to do anything on it was almost impossible.

EVA would not help with ticket issue since they were purchased through a travel agency. Even though it was EVA ticket stock. Travel agency Budget Air didn't reissue ticket after airline change which I didn’t learn until trying to checkin on Christmas Day and there was no contact number for the agency to help. I will never use Budget Air to purchase flight again and disappointed in EVA’s refusal to help. Thankfully just under 12 hrs before departure someone from the agency was available to reissue tickets. I was starting to think we would not be flying and the stress trying to resolve was completely unacceptable.

seamless check in/ friendly staff, food is good, always love flying Eva Air

Very uncomfortable and crowded seats in economy. Flight attendant refused request to move to nearby unused seat with more legroom because “It was more money for that seat”. It was also near impossible to reach airline directly by phone. Waits upwards of an hour and not very helpful customer service representatives after long wait. Cannot recommend this airline.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

The food options and quality could use some more excitement and variety.

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Leg room and flight sound insulation is very bad. They broke 3 of my bags with bad handling

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.
