Delayed and took off even later than the scheduled delay time

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

It was a disaster. The crew was so rude and had no professionalism. She dropped something onto the floor, then took it from the floor and put it into the food tray. Also, when she got some spilling, she went straight to the toilet, got some tissue and started cleaning the food trolley

I cant wait for planes to have shorter rows with more space! otherwise, all fine thankyou

They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Damage lagguage, They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

Apart from chaotic boarding - which I totally understand was outside the control of gate staff. It was comfortable mid haul flight. Well done to cabin crew for their patience and hospitality with largely elderly passengers returning from pilgrimage.

The intettainme is old stuff and difficult to get by WiFi and the chair is not comfortable at all although the staff were excellent but beyond their limited

Overall a great experience, no movies were available. Bags were delivered a bit late. Seat controls were not working well. I couldn't make my bed fully flat.

It is almost 7 hours journey ,you should have provided with TV entertainment and mobile charging

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.

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.

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

Hate their old flights, boatding, food and services. Very poor quality

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

The food could be better, more snacks. And have some plugs to chargue the phone.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Seating was average for a first class seat. It very modern. I expected better.

Flight was a little late. The crew was courteous, food ok

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

Extremely pleased with the crew. Best flight attendants ever! Very friendly, genuinely caring and attentive.

My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Old tired plane, Uncomfortable business class seat. Breakfast dreadful and meagre. At least flight was on time!

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

They removed our booking without telling us. Cost us thousands to book last minute

Enjoyable flight, helpful crew everything was organized to accommodate passengers.

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The international flight from PHL to Lisbon was one of the worst I’ve experienced, ever. What was really disappointing was the entire experience of comfort and service in the coach cabin after takeoff. The food was inedible and the wine served with dinner was such low quality - it tasted of petrol. I couldn’t eat more than a bite or two of the chicken entree, being worried it would make me ill. The service took so long to reach the entire coach cabin, I ended up having the lights turned off on me as though I had to rush though dinner (though as I mentioned, it wasn’t as if I ate much - only the salad). Most of the attendants seemed generally annoyed and were not friendly or polite. While there was some turbulence, it wasn’t too uncomfortable and I know that is just a chance. The temperature of the cabin was so warm, even a friend a row or two up and on the other side of the plane felt like this. To top it all off, the seat was so uncomfortable and flattened/overused, I had back pains for DAYS afterward.

They’ve lost my bag and I have no way of really getting in touch with anyone and have received no updates.
