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.

  • 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.

Airline reviews

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

I put the review all together for the first review

The crew need to be more friendly it seem everything such a rush situation during dinner and breakfast. Smiles to the passenger go such a long way just the service from Seattle to Taipei, service from Taipei to Bangkok were great more pleasant the flight attendant from Thailand she was very nice, as far as entertainment were amazing , wiffi connection was incredible great, I will be able to charged my phone from Seattle to Taipei and from taipei to Bangkok I won’t be able to do so flight attendant told me that because I don’t have the original iPhone charger connection has nothing to do what type of charger I have so she said there is nothing she can do about it. Foods : from Seattle to Taipei were ok no flavor , from Taipei to Bangkok I have chicken teriyaki the rice is overcooked all the flavor stuck on the aluminum wraps , breakfast the congee was on point and delicious. Will I recommend anyone to fly with Eva air go for it so you can experience yourself for myself I won’t fly with them again I’m gonna stick with Singapore airlines instead.

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Never went. Got rescheduled with Phillipine Airlines to Bali, which was fine.

I am really satisfied with Eva Air and will definitely fly with them again.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

The flight from SEA to Taipei was on a Boeing 787-10. Economy seats were unacceptably cramped and the seats themselves were old and lacking cushion. I'm only 5'3" and couldn't cross my legs as my knees were up against the seat in front of me! I could not get WiFi to work most of the time on both flights and crew were invisible except to serve meals. The onboard entertainment also did not work reliably and was very hard to hear through the provided earbuds. The Asian vegetarian meals were interesting. I hope they can provide a fully vegan option though these meals seemed to be already. I appreciate their providing these meals options for vegans. I don't think I'll fly a 787-10 if I can help it. It was the definition of a sardine can in Economy.

My luggage was lost and didnt arrive in manila yesterday. And until now im still waiting for the confirmation if my luggage is teady for pick up in terminal 1
