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.

I put the review all together for the first review

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.

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.

Very nice, I feel I got good value for the price.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Good. Please add a non- applicable category to your questions.

Amazing crew, excellent food, business class seats seem a bit dated but are super comfy even for a very tall person. If continuing onto Taipei, the stopover in Bangkok is a bit annoying (queue at security) though the lounge is decent.

Everything was fantastic! It was a short flight but the crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Delayed due to no fault of flight crew. Efficient and worked well together.

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

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Cabin Crew was excellent. They took care of everything requested. Flight was good

The ROOM was great. We would love to have it on all of our flights. LOL

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.

The pilot was kept warning about the weather terrifying us. The flight attendants were not warm or pleasant.

Flight was good and comfortable, even for long haul economy. No complaints.

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

Everything was good may improve some alcohol drinks and amenities during fly

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

The crew was very inconsiderate and rude. My flight was scheduled to depart at 6:00am. I received a call from the crew at 5:40am, asking if I was going to make the flight because I was the only one that hasn't boarded yet and boarding ends at 5:50am. I let them know that I will be at the gate in a few minutes, before the 5:50am cutoff. When I arrived at the gate at 5:45am the gate was closed. Departing early on last minute notice without having all passengers on board is inconsiderate and unprofessional.

Very easy to use and convenient, you can perform any action within the same portal

Okay considering we had weather delays which the Pilot notified us of immediately!

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Stop changing gates. Stop cancelling flights Stop moving my seat.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

It was very cold because the air conditioner was on high power, and my son got sick.

Horrible. Flight ORD to CGH was okay, but Paris was a nightmare. Old planes, delays, involuntary downgrades, broken planes, terrible communication. CGH to CPT was my worst flight ever.

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

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

Everything was fine and I have no complaints or things to note.

The economy seats are much indeed roomier. Meals needs improvement.

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

From Chicago to Hong Kong was great., but from Hong Kong to manila we had hard time looking for the gate of our connecting flight. There wasn’t hardly any sign.

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

The kid in the middle seat kicked me almost the whole flight, almost kicked my hot tea off my tray. The flight was delayed due to the first plane not being able to be de-iced in July! We had to get a new plane. Now I drive 3 hours back to Edmonton because direct flights from PVR were way to expensive

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

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

Staff members were not helpful they ignored all calls for an attendant.

Is ANA airlines not united airlines, ANA airlines crew working professionally , more services providing, happy face to service customer
