  • You may travel to South Korea from any of the major international two airports - Incheon International Airport (ICN) and Gimpo International Airport (GMP). Gimpo International Airport is closer to Seoul and serves the majority of domestic flights. Incheon is experiencing an increase in international aviation travel.
  • O'Hare International Airport (ORD) and Chicago Midway International Airport (MDW) are two of the city of Chicago's main international terminals. Both of these airports are major international airports located within the Chicago area, with each of them serving as hubs for major airlines based in the United States.
  • At O'Hare International Airport, there are lounges and waiting places, with one in each station. For the duration of your stay at ORD, you are invited to use these lounges. Additionally, Chicago Midway Airport has lounges at each of the terminals for its visitors. For the comfort of the visitors, these lounges offer charging stations, and showers.
  • Traveling parents may breathe easy knowing that the O'Hare International Airport provides a cozy nursing lounge where they can feed their kids or moms can breastfeed in peace. The nursing area for the airport is located in Terminal 3's lobby, which also houses the airport's yoga room and urban garden. There is a Mother's Room at MDW for breastfeeding mothers who prefer a more private situation. It offers a sink and some comfortable seating in addition to a place to wash up and unwind.
  • Both the airports in South Korea and Chicago provide extensive amenities for passengers with impairments. For both airports, you should reach out to your airlines in advance of your travel to ensure there is sufficient time to plan and support your needs, or the needs of your travel companions. You can also ask for help with renting a wheelchair or navigating the airport terminal when you first go to the airport, when you leave the airport, or even after you have already been there.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

Korean air has a little bit more seating space than Asiana air.

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Not many people, so you can lay down on two seats

Cramped seating for me. Luckily it wasn’t a long flight

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

The airport was reasonably clean. The boarding process reasonably efficient. The cabin crew was efficient, polite but not that friendly. The food quality was unremarkable and the choices were awful . There was either a so so chicken dish or a “ vegetarian “ option which was really cheap carbohydrates drowned in cheese. Signing onto i flight wifi was not straightforward. Overall it was a very average experience

The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

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.

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

they are deley vancouver to hankong 3 hour after honkong 20 hour stay there honkong not visa approved and they cant help to visa so we are stay in airport 20 hour even honkong staf very bad person they cant do for us 6 hour we arround they said you there you go there waste time next time i dont want to go cathay stay in honkong

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

The only problem I had was not being able to download my boarding passes prior to arriving at the airport. Everything else was perfect.

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

I was not given basinett seat.The connecting flight was missed due to airline fault i was not accomodated for hotel.Drinks were normt served frewuently.Never travelling again on tirkish airlines.I always travel wiyh family by turkish airline but no more.zero stars

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Bough tickets with luggage, but made me pay at Airport as well

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

Didn’t realize I purchased a basic fare with no carry ons allowed. Not very well communicated. Also had seats switched without knowledge and had to pay for different ones.

We loved our Air Canada experience and will definitely fly them again. It just so happened than in the first leg of our trip their entertainment system was not working, and neither was their oven so cold meal & snacks only.

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

There labor disputes cancelled my flight less than 24 hours before my boarding time but there customer service/website was easy enough to navigate and they rebooked me for no upcharge.

Very bad, flight was cancelled due to strike and staff was unable to rebook us

Flight was delayed by 1.5hrs. Once inside, people had their small handbags on the storage. The crew (male guy) was not helpful in making some space in the storage. Instead, he asked few bags to be checked-in and it was not a great experience. No attempt to help but just followed the things with a straight face. People had their literally small bags and he wouldnt not move from one storage to another even if there was space and would not let us do i as well. Once flight was on, they ran out of Orange juice, really running out of orange juice when the temp were 32.degrees outside. didnt made the sense. Onasking for a extra snack, he made a face as if he was giving me out of his pocket. if the flight was delayed, there could have an attempt to provide something extra incase people did asked.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.

Conflicting information provided about baggage allowance. One screen said I had a carry on and another said I didnt.
