Reviews of the top 5 airlines serving from St. Louis to Europe
The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

Your survey needs a N/A option. I didn’t use the entertainment or eat food.
Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.
Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable
From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.
Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!
My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.
They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.
The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.
We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.
Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.
On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.
The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.
I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.
Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.
HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.
Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.
Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.
Onboarding - it would be great to see on the screen what group they were boarding. It was very confusing on who was boarding (even though they called it out) they were not clear and the space to board was strange.
Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.
My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience
American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.
Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.
Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.
No enough space plus only allowing one laggage instead of two like other airlines.
Qatar airways ,boarding arrangements at Hamid international airport could been better
Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.
Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs
Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.
First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.
Old planes and rude crew. They need a make over and better staff training. Even business class crew was rude and the hospitality was non existent.
They left a little late, contributing to our missed flight.
Great. Only issue…the cabin was kept as warm as a sauna.
United did a good job of communicating before the flight, but a simple notice about the expected time for the completion of repairs to the broken navigation services (which closed the airport for the day) would’ve helped to clarify our expectations. With so many cancelled flights on the 21st of September, a little certainty about our own departure would’ve helped. Because of the disruption, the plane was quite empty, and at 6‘5“ I was able to steal a little extra legroom from the empty adjacent seat. However, I am still waiting for the day when I can sit in a standard economy seat and simply straighten my legs. Cabin crew were amazing. Great attitude, and moments of fun with passengers.
Perfect airline, super friendly, great service, tasty food. Would fly again.
The flight was delayed more than 1.5 hours. Phone calls to united did not satisfy our need to get to Chicago to met family for fight to europe. I was told the flight was booked thru luftansa and united could not make adjustments. When call luftansa they were unaware of the significant delay on the united flight out of mci. They would not authorize a flight change. We went to the airport, as if we would be flying as scheduled, United checked us in, as if our flight would leave as scheduled. We took our bag to be checked to the baggage drop and the agent their confirmed our flight was significantly delayed. She worked for 30 min to get us on another flight. We ended up flying to Denver then to Munich. The rest of the family that flew to Chicago for our meet up and flight to Europe ended up flying to Munich alone. We meet up in Munich for our last leg to luxembourg. In luxembourg we learned on bag was scheduled on our delayed flight. The flight was canceled and we did not receive the bag in lux. We filed a lost back claim. Now 3 days later we STILL do not have the bag. It is apparently in luxembourg and they maybe tried to deliver, however the names on the door of the air b&b do not match the name on the baggage claim so the French speaking delivery person called no one could understand him so he took the bag and left. My brother, traveling with me under a different reservation , has been without essentials for 3 days. One or all of us has stayed "home" each day waiting on the bag. Today was my turn. Delivery window was 10:30 to 2:30. No attempt to knock or ring bell. After the hang up call, my brother called me and told me to check the door. There was nothing there. No sign of attempted delivery, no delivery man, nothing. Being unable to change clothes and having family members take turns waiting on a bag that never comes has ruined this family vacation. Thanks United/Luftansa
The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.
The The check in process was terrible on both ends. It was not clear if we should use the United, Lufthansa, or Aragrant number. It took over an hour to check in on the front end – and then at return the Lufthansa online check in failed multiple times and only after two calls to their phone number could we accomplish the task. The link to the Kayak site provided no access for check in. This difficulty and ambiguity on both ends will affect our interest in using Kayak for foreign travel in the future.
You lost my bag then waiting on the phone for 30 mins for customer service just to be directed to call another number
Boarding staff, crew and food needs a lot of improvement!! It was awful Aircraft was old with minimal legspace
I chose seating based on me being 6’3 and they changed planes I guess bc I got 2 random Seats that were middle and window and vert cramped and uncomfortable for a long flight….should have been able to get same seating just different aisle maybe especially since we picked them and weren’t random
Liked that our agent at check in changed our seats to allow us to have more space.
Check on was very hard. I believe my seats had been selected when I booked, but when I checked in I had to select seats. My previous pre assigned seats were no longer showing and I had to take seats I did not want. Check in took me forever. I also had to pay an additional 22/seat when I had already paid. Lastly thought I had pre paid for a checked bag., but that did not show up so I had to pay for a checked bag. 75.00????
Waited until boarding started before saying there was no overhead luggage space on the plane.
Late lights, lost baggage and cramped seats. Did not feel that lost baggage was a priority. Communication was slow and often unclear.
Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.
My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.
Our flight from ORD was cancelled and BA rebooked is on a flight that originated before the time that they booked us on it. They did not realize we were already arrived in Chicago. Then American Airlines helped us get checked in to the new flight (the one BA assigned to us) which flight we did take although it was delayed about 2 hours, and our assigned seats that we paid for - on the original flight- were lost we did at least get to sit together. It was not too painful for all the changes and we made it to the UK alright though all in all with all the delays and cancellations the flight took about 20 hours to get us here.
though there was space in the cabin they asked us to check in our trolleys. As a result lots of things arrived damaged in Larnaca. They were fragile. When we asked the attendants why that.....they said talk to the captain!!! Unbelievable!
Boarding ,checking in was easy and quick . Comfort was not good.
