Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Very old plane on the Istanbul to Bangkok flight, had an emergency exit isle row, no where to put anything, on a plus point loads of leg room. Food was the best I have had in 39 years of flying.

Absolutely horrible experience. It's an overnight flight for over 5 hours and business class does not have beds!!!!! I had a slightly bigger than economy class seat that was broken and not even reclining correctly. I should get a refund for this flight as they changed the aircraft to a small one and that is not what I paid the business class price for!

Professional & courteous cabin crew. Food was very good even in economy class

This time my experience was very bad. The Turkish Airlines changed my flight from Erbil to Istanbul from 8:15 AM to 11:20 AM few days before the trip. This made my transit in Istanbul about ONE hour. I have a special needs child and need extra time to navigate the huge new Istanbul airport with a child. To make the matter even more stressful the flight took off about 20 minutes late from Erbil which made our transit even shorter (around 40 minutes). The Turkish Airlines failed me on too many points despite clearly asking for help and as follows: 1. I asked the checking agent in Erbil for seats at the front of the plane to exit first and he stated the closest one is in the middle of the plane and I should ask the flight crew for help 2. I asked the boarding agent in Erbil to ask the flight crew to let us out first since we don’t have much transit time and she said she can’t and they wouldn’t listen to her anyway. 3. When we boarded I specifically asked the cabin crew chief the same request and after some discussion he wanted to get rid of me and said, they will help when we land. I again politely reminded the same person to help us when we exit before landing and this time he stated he would NOT be able to even announce to the passenger to let the people which short transit first and I should just deal with it like other passengers. He also told me to ask for help from the airlines staff at the gate when we get to the airport. This is very rude coming from the Cabin Crew chief. 4. I asked the airline crew at the gate which he had a cell phone to call the gate of my flight to inform them we are on our way and the agent pretended he didn’t speak English… Frustrating 5. I went to the Golf Card station (used to transfer passenger in the large airport) and asked for a ride and the driver there “shooed” me away pretending he doesn’t understand English while looking into his phone constantly telling me “Go this way, Go this way”. I saw first-hand other well able passengers on these cards and Turkish looking families get help on our way … which is clear discriminations. 6. We finally got to the Gate as one of the last people and we didn’t even use the bathroom on our way and made it back to Canada. I am extremely frustrated with the TKY this time and feel discriminated against just because I look from the Middle East despite I am and my child are Canadian. The Turkish Airlines operations failed me on too many points this time.

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

My flight has been changed twice so far. Disappointed with Turkish!

Internet connection was very weak, did not connect at all. Seat comfort was poor, buttons didn't work properly. Overall not impressed in business class.

The flight was delayed both legs of the journey. The seats were cramped.

The plane is cramped and there is no space to move. The seats should not recline because when a person in front drops their seat you are trapped and you can't even see the entertainment screen because it is right in front of your face. I like that checked luggage is included. The food tasted good but they ran out of breakfast choices. The crew is nice.

Pegasus Airlines which is the most efficient and cost worth low cost airline all over the Europe

Flight from London was delayed and we had to hurry up to catch the connecting flight to Riyadh

The crew were outstandingly kind and cheerful. We carried our cat and they offered help.

Late departure. No announcements. Boarding was a disaster. Some kind of technical issue scanning boarding passes.

Pegasus is a very efficient airline. Passengers, however are sometimes unruly. Getting up right after take off. Getting up right when we land and before getting to the gate. Switching seats to the front so she can get a better seat. It is unfair for those that actually paid for seats. Flight attendants seem to not enforce it. One or two bad actors ruins it. Overall, the airline is great.

Pegasus is not a very comfortable airline. They’re not in any way hospitable

It was like moving cattle around. Very abrupt, uncomfortable and not much hospitality

All good but air not give the pasing er any food even glase of water

Flight delayed by 1hr when we already boarded because someone had to get off. Leg room is terrible for 6ft people like me.

I used the airline 5-6 times for the last year and every flight have had perfect timing and I like it. Despite catastrophic absence of space for my legs 😁

I am not sure I like the new Discover line of Lufthansa. I have been flying from us to Italy for the past 30 years and always favored Lufthansa ove other Companies because of cleanliness, service, food, beverage. When compared white other airlines Lufthansa was always considered one of the best. I can't say that anymore. I fly Lufthansa only because I consider the line MCO to FRA timely convenient for my schedule but always look for alternatives when before I was considering other routes only if the price was in question.

SAL to FRA - Original flight was cancelled less than 10 hours before scheduled. Did receive lodging at no cost for 1 night. Coordination between Lufstansa and hotel was very poor and we had to pay for a meal we thought was to be paid for. Traveling from SAT to Denver coordination between Lufstansa and United was very poor and we paid double for our check-in baggage. We are hoping to that refunded. We wish other airlines would fly to Salzburg as we plan to visit more often.

I was charged for one of my luggage twice, when I was not supposed to be charged for it

Lufthansa crew are great Frankfurt to Raleigh RDU North Carolina USA

Boarding delayed 1.5 hours. Ended up sick because of all the delays and lines waiting around airport and boarding.

One shocking event is worth noting. I told a crew member that someone in the row ahead of us is listening to their iPad without earbuds. She looked and me and said "yes, so?" I asked if that's now allowed in Lufthansa flights and she said that it is. If this is true, I don't know how Lufthansa plans to control the coming cacophony of people listening to different things at the same time and driving the volume ever higher to drown our their neighbor's personal device.

Leg room is good, food is average, crew is not friendly

Gate was difficult to know. Flight number from Lufthansa directed to a different flight number by SunXpress, which was different from my actual flight per the airport. Multiple people (at least 3 others) were lost with me at the airport in Munich (I didn't know them) trying to get to a different terminal. Too many confusing signs, and no one could help. When I found some Staff members (surprisingly difficult) told me "you have to figure it out." Yeah, that's why I'm asking and walking around in circles. Thought I would miss my flight, turns out I had plenty of time, but I couldn't figure it out for the first hour. 90% airport's fault, not SunExpress.

The main issue was every single flight and connection was delayed. That made for a very stressful run through Frankfurt airport both ways. Other than that it was much better than other cheap flights, but basic. The cabin staff were great.

Getting boarding pass for international connected flight was a hassle. Huge libe to get boarding pass after two connected international flight is excessive to put someone on stress. They should provide online checking for all flights

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

Awful! First off, 15 minutes after purchasing my tickets I received an email to purchase my seats for the flights I paid for, charging me an additional $400 plus to be able to sit with my wife. Then, our flight(s) were late leaving 3 out of four times from the origin of flight (PDX, BUD, LHR). They couldn't even load the airplane to balance, had to wait 45 minutes to reload. After being late into Heathrow, they didn't have the personal to get the gate extension to the plane. Made our connections very tight, made us run from gate to gate. Not to mention Heathrow is one of the worst airport to connect from(if you can use Frankfurt or Amsterdam, they are both superior to the dump London is) event hough it is BA's home, the gate personal was rude and very stuck up. After running through the freaking airport, taking a bus, train and 3 elevators covering 7 floors in all. On our return to Portland, the service to Portland from Hawthrow was great, especially Chris, who was very aware of everyone's need and pleasant throughout the flight. This was my 3rd and final cross Atlantic flight with BA. Each time they were marginal to say the best. Their personal both at the Budapest and London stops were awful and made me flying with them poor. I will avoid BA and Heathrow at all cost if I can.

Brand new plane and excellent customer service, also on time departure and arrival at LHR.

Very disappointed late takeoff led them to rebook me on American and United. The latter was cancrllrfg

Bathroom was out of service. Had to pay for everything

Business class to Istanbul. Packed flight. Cabin crew seemed incapable of differentiating between economy and business passengers with regard to access to the WC which meant whole flight I had people standing in aisle and leaning into my aisle seat, queueing for the front WC. Crew put it down to a lack of curtain between the two classes. The seats, for a 3hrs55 min flight were just standard seats with middle seat unoccupied. So nothing special apart from the food, which was mediocre. Aside from the roast chicken dinner (‘special’ traditional British menu option, which looked poor but tasted good I gather). However 2 king prawns does not make a main course salad.

First flight was 2 1/2 hours late. Had to wait in line on the tarmac for 45 minutes to finally board. Missed connection. Had to wait in line another 2 1/2 hours to get booked on another connection the next day. Another hour wait to get a hotel room for the night. 1 1/4 hour wait in 55 degree temperature for hour bus ride to hotel. Hotel ran out of food. Miserable performance by BA. This is being written while waiting for bus back to Heathrow.

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.
