KAYAK’s top tips for finding a cheap flight from Chicago to Bangkok Suvarnabhumi Airport

  • Chicago is served by two airports, Chicago Midway International Airport (MDW) and O'Hare International Airport (ORD). To fly to Bangkok from Chicago, you'll have to make your way to ORD, as it is the only Chicago airport that offers flights to Thailand's capital. On the date you're set to travel to Bangkok, you should get to the airport at least 2h before your flight. This will give you enough time to navigate the traffic you'll encounter while entering the airport, go through the airport's security checkpoints in time, and check out the superb destinations scattered across the airport's terminals.
  • To be able to easily buy things and pay for services you receive while in Bangkok, before boarding your flight at ORD, you should convert your American dollars to Thai bahts. At this airport, you'll have an easy time doing so, as it boasts numerous currency exchange sites. They are near gates B9 and C18 in Terminal 1, the Main Hall in Terminal 2, gate K11 in Terminal 3, and the upper and lower levels of Terminal 5.
  • While waiting for your flight at ORD, you can enjoy relaxing spa services at the XpresSpa, near gate M10 in Terminal 5. You'll enjoy remarkable spa services at this spa, open from 9 am to 9 pm, as it features incredibly experienced professionals and state-of-the-art spa equipment.
  • If you land at Bangkok's Suvarnabhumi Airport (BKK) later than you expected, you can choose to spend the rest of the day at one of the comfortable hotels located within the airport's grounds. These hotels include Miracle Transit Hotel in Concourse G, Avagard Capsule Hotel near the Airport Rail Link, and Boxtel, situated a short distance from Airport Link Suvarnabhumi Station.
  • The popular layover destinations between Chicago and Bangkok include Tokyo, Amsterdam, Munich, and Dubai.

Great food on both legs and fast customer service from the stewardesses....

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.

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.

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

Staff at gate and crew on plane efficient and friendly.

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

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

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!

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

It was good. The crew was efficient, food was good

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Connection flights should be spaced out farther because too close I missed my connection.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

Very attentive crews Flight was very smooth and safe Only little disappointment was the slight delay of departure (~30 minutes ) which rarely happen with CX flights

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Later on, when there was no more bottled water, the water we received had a strong chlorine/disinfectant odor. On my flight from Hong Kong to Los Angeles, there was a male flight attendant who had a mean attitude throughout the whole trip, and he was very impatient during meal service “Furthermore, we purchased a Hong Kong SIM card as part of our flight package, but we received no instructions—neither by email nor SMS—on how to activate or use it. Consequently, we were unable to use the service at all. We request a full refund, as this appears to be a deceptive charge

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

Poor communication, flight was delayed for preventable reasons. I missed my connection.
