FAQs - booking Thailand flights

  • How do I get from Denver to Denver International Airport?

    Driving or taking a taxi from Downtown Denver to DEN Airport is the fastest option. If you decide to use any of these options, you will arrive at the airport in approximately 30 minutes. If you choose to drive yourself, factor in an extra 10 minutes for parking. Alternatively, you can opt for RTD's A Line, which takes about an hour to cover this distance or a train that will arrive at the airport in around 40 minutes.

  • Are there any on-site hotels at DEN?

    Staying at one of the airport's on-site hotels is recommended if your flight out of DEN is scheduled for early in the morning. The nearest hotel to the airport is The Westin Denver International Best Airport Hotel, which is also a practical spot to stay. You won't have to worry about the airport commute because the hotel is close to the main terminal and offers a complimentary shuttle.

  • What is the most efficient way to travel from BKK to Bangkok?

    The quickest and least expensive route from the airport to downtown Bangkok is via the Airport Rail Link. When you get there, follow the directional signs to the train station, which is on the ground floor. In about 35 minutes, the train will take you straight to Makkasan Station. On the other hand, a taxi takes approximately 25 minutes to cover this distance, while a bus takes 1 hour.

  • Is BKK airport pet friendly?

    Yes, BKK is a pet-friendly airport. It features two pet relief areas on the outside, on either side of the Baggage Claim area. However, when traveling with your pet in Thailand, you have to follow the pet regulations of Thailand that you can find on their government website.

  • How does KAYAK find such low prices on flights from Denver 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 Denver to Thailand.

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

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from Denver to Thailand is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from Denver to Thailand?

    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 Denver 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 Denver 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 Denver to Thailand 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 Thailand

  • If you are flying out through Denver International Airport, you should arrive at the airport at least 3 hours before the scheduled departure time. This way, you will have ample time to go through security screening and arrive at your gate on time.
  • Mamava lactation pods are available at DEN Airport for any nursing mothers. The first one is located near the arrivals gate in Terminal Level 5, and the second one is on Concourse B on the far East side.
  • Upon request, individuals traveling from DEN to BKK can access services for persons with limited mobility. Be sure to inform your airline or travel agent 48 hours before your scheduled flight time. Both airports are equipped with wheelchair shuttles and restrooms for easier navigation. Further, you can get extra assistance throughout your travel experience from gate to gate.
  • No matter which airline you are flying with, customers can access lounges at Bangkok Airport (BKK) at a discounted rate. It's a simple option for breakfast, an early morning check-in, a canceled flight, or a connecting flight. If you have some time while waiting for an airport transfer, visit one of these lounges and relax with a cup of coffee or a good meal after your long flight.
  • When scheduling connecting flights from DEN to BKK, be careful to choose an automatic transfer rather than a self-transfer journey. This is because self-transfer flights demand you to check your baggage and personal items each time you fly.

The seats weren’t comfortable and the foot rest was broken.

I liked the space of the bathroom. The seats were not as comfortable for such an expensive cost the the foot rest was broken. A small child cried for several hours and I thought the FA would have assisted the family to calm the child.

STARLUX Airlines has great staff and crew. Well organized for quick boarding of such a large plane out of Phoenix to Taipei. Interior of the aircraft was that of deluxe aircraft.

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 😫

amazing and great food. everything was smooth from start to finished

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

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!

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

Everything was smooth and professional. They could improve the raw vegan meal with fresher offerings, but otherwise they are now my favorite way to fly to Asia.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

One of the business class panels where we were sitting was broken and it didn’t close. Therefore, the be privacy was limited.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

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.

As usual the flight from AUS in Austin to SFO was late because they didn’t have adequate staffing to board the plane on time creating a 1 hour delay, which resulted in me missing my flight to Osaka due to a missed connection. When I got to the gate 10 minutes late after landing exactly the time the connecting flight was taking off, I saw my flight to Osaka sitting at the gate and that gates had closed. I attempted to contact United Via chat on the United App and was given the runaround and passed between 2 separate “agents” who after saying they could rebook me, told me I needed to go to ANA even though they’re partners and all of my ticketing was through United. After going to ANA’s gate at SFO to try and get help I was told I would need to leave and go to United’s ticket counter in order to get help. The ANA agents said that it was United’s issue. An hour after running to try to make my flight I got to the United counter. I showed the agent my itinerary and she helped as much as she could. I was booked on a flight that would occur 13 hours after my original flight to Osaka and given $45 in vouchers which doesn’t cover much at SFO. I had also spent 30000 miles with United to get an upgrade with more legroom. And that was not refunded to this point. Ultimately I lost 1 whole day of vacation in with my wife and kids and, the 30000 airline miles and I’m out the money and time I spent. In these situations United and their partners should go out of their way to communicate and accommodate but I was left to my own devices to find the right resources. The only option was to fly to Seoul 12 hours and take a connecting flight to Osaka: I am a United Skyniles member and would not recommend booking a flight with them unless you thoroughly understand the routes as it is likely you will be left to your own devices to resolve the situation.

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Suck! Sat in plane on the tarmac (hot) over 2 hours

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Lost Baggage - very frustrated…learned that bag was never put on plane.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

2 hours delay on the 1st plane out of the day!!!!!

Multiple delays, with no explanation. Caused us to almost miss our connector. The airline made no effort when we arrived in Shanghai to help us make it to our next flight with the same airline.

A lot of value considering the cheap ticket prices. All meals served were Chinese food. Would fly them again considering the ticket was half the price of any others

Multiple delays and flight cancellations meant that I arrived five and a half hours late at my destination. There was limited communication from the airline. The airline left my checked bag at my departure city and stopped tracking it almost immediately. The airline has made no apparent effort to return my bag despite filing a report, and has provided no communication or ability to check on the status of the bag.

Food options were ok but the actual meal was terrible. On my way back, they simply said that there was no vegetarian option; somehow they struggled to get one meal and did not give me any breakfast at all which in my opinion was terrible. Never had such an experience in the recent years.

1didnt have wheel chair I ordered wheel chair in my ticket flight

Extremely disappointing. My original Denver–Vancouver–Bangkok itinerary was cancelled due to a crewing issue. I was not proactively supported and had to drive back home after already reaching the airport. Communication was poor throughout, and attempts to contact customer service resulted in being on hold for nearly three hours without reaching anyone. Instead of being rebooked on the same direct routing the following day, I was rerouted onto a much longer itinerary via multiple cities and airlines, which resulted in arriving approximately 30 hours later than scheduled. At Denver airport, there was no visible Air Canada representative available to properly assist. Ground staff offered no real support beyond directing passengers to a phone number. There was no clear communication, no ownership, and no meaningful customer care during a major disruption. The final journey involved three flights instead of the original two, significantly increasing travel time and stress. Overall, the handling of the cancellation and lack of customer support was unacceptable. What could have been better? Clear communication during the cancellation Accessible customer service (phone support that actually answers) Proper in-person assistance at the airport Rebooking onto a comparable routing rather than a significantly longer one

We had a very long delay. First the inbound flight took a while, then maintenance, they “fixed it” to then do boarding and leave the gate, and waste a lot of time to have to go back to the gate and eventually deplane. Had to wait for a new aircraft, wait for a gate, and do the whole thing again. Instead of leaving at 9:50am we left until past 1. I could’ve not woken up at 5am, or spend some more time with my family if they gave more grace period of time between flights to give some time in case of any issues. But they have to make all and every dollar possible

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience. Flight was delayed then canceled. They had no clue how to rebook us. Had to wait in line to take to a gate agent for 2 hours. Absolutely terrible from start to finish.

Most expensive flight… and they are trying to pinch more and more money out of you. Baggage, snacks, pillows, headphones… — so many airlines do far better than this… surely a national airline can do better?

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.
