Great quik boarding, friendly gate agent and crew. Let early

We sat at the gate for over 30 minutes, with no indication as to why

All was fine. Small plane so no food or entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

I love how the flight crews are now saying what the weather will be like, when we can expect to be able to get up and use the restrooms etc. I have to say also that our flight crews this trip were incredible - fast and courteous - and somehow managed to do the service even on these short flights with a few bumps. The only reason for an ok rating on entertainment was because these short flights are on planes without seatback displays but that's ok because I just download shows on my iPhone beforehand.

Our flight from Detroit to LaGuardia on Thursday 8/20 was delayed from 555 to 910 due to storms and a ground stop at LGA. It’s never fun to be stuck at the airport but I thought the desk crew and captain handled it well and kept us informed. I especially liked how they referred to us as their “LaGuardia family.” I am a loyal delta customer and this is one of the reasons why.

The plane is old. There was water dripping fown from the air cooling system. The toilets were mot that clean

The meal tray was not usable it was completely uneven

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

The taxi drivers are very rude. Didn’t wait. They said you come in 5minutes or I leave. Did not leave any messages on front desk and they left. We have to hire new cabs in turkey.

Everything was good except for the seating arrangements. We could not get seats to be seated together with my wife. We’re unfortunately.

My first time in business class The in flt staff was outstanding in every aspect of service, the food was amazing, the business seat space made the 11 hour journey easy peazy

It was good, but always can be better. The airplane was old.

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

short flight but we still got a very nice lunch and the crew did an excellent job in taking care of us

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

Was an excellent experience I have been flying Turkish Airlines for 5 years and always will

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

This flight is a quick way to get to Chicago, but a bit expensive.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

Staff friendly and app worked really well. Modest delays were frustrating

Our flight was delayed 3x and we were unaware until 15min of arriving at the airport so had we been made aware sooner we could have enjoyed possibly another 4hrs poolside. Very frustrating. Made the next day going back to work extremely tough too.

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

I like the idea of a non-overnight flight to Europe.

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

I was very frustrated that our first flight from Grand Rapids to Detroit at 6.20AM was cancelled because the captain wasn’t legal to fly. Especially after the fact that we all had already boarded, then had to deplane. I was excited to fly to Korea for the first time with Korean Air for a connecting flight, but had to give that up because of Delta’s mistake. Not only that, but I wasn’t even able to sit with my dad on the longer flight. Our first flight after being changed was also delayed because the captain had to take an uber. The only compensation we got from this giant mess was a $12 airport expense voucher that I didn’t even get to use since we didn’t have enough time between connecting flights.

We didn’t make the flight due to Delta’s check in line moving too slow.

Flight was delayed four hours! No on board entertainment fir a four flight. Minimal food

20+imite delay on the plane with no air. Part of our group had no seats assigned and took a long time to get fixed. Again no wifi and snacks were sad

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

On board Entertainment and crew services were absolutely trash! Neither me, nor any of my 40 family/friends members are flying Lufthansa again!

Plane was delayed for over 1 hour causing us to miss a connecting flight in Munich. We spent 10 hours waiting for the alternate flight which was delayed about 45 minutes. We had a service attendant who was very helpful with our missed flight. Later in the evening when consulting service attendant, he basically said, the plane will show when it shows!

Food should be provided according to the passengers selection. In flight entertainment system must be updated with latest devices and applications. Proper over head headset must be provided rather than providing cheaper ones.

Very organized check in and boarding experience. Good crew very helpfull.

Deplaning at Frankfurt required ck=limbing steep stairs with no provision for escalator or elevator.

Flight comfort was good. However, due to delayed flight, waiting was too much while boarding. Moreover, food choices can be improved as well.

Flights on time, planes up to date with clean toilets, comfortable seats and working IFE. Helpful Lufthansa staff. Food was good, but can always be better, esp vegan and vegetarian food loaded from the USA. Overall great experience.

We were on a new plane with Lufthansa and everything was clean and seats were comfortable. Staff was courteous and food was good. The only airline that still provides real silverware and not plastic.
