Airline reviews

We arrived in line for check in at 6:15 p.m. but did not check in until 8:00 p.m. The line for economy check in was very long, and all of the desks 03-13 were not open, although most of them opened sporadically. The crew on board were very nice and helpful, friendly and kind. It has been many years since we flew Emirates (at least 17 years), and we notice that foot rests are no longer available in economy, but we were lucky enough to fly in the upper deck and appreciate your opening some of your flights to economy passengers in the upper deck. We will definitely fly on emirates more often! Thank you.

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

Flight left on time. Bags came quickly. Crew was nice. But internet never worked and the food was awful.

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Poor flight aircraft very old Crew was friendly 1 person though

Flight was on time. Seats (economy) were very comfortable and food was excellent. The bad thing was that after landing it took an hour to reach arrivals. We had to wait 15mins to get off the plane and then had to board a bus which moved very slowly and took almost 30 minutes.

Emirates is always a pleasure to travel on. From the spectacular First and Business Class configurations of your big A380 and 777, to the Bar Lounge to, of course, your impecable on board flight attendance and their iconic uniform, now also even available for young girls. All the destinations that Emirates offers makes it an airline of choice many a time.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

There was not enough food for everybody. Some dishes were missing.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

Being a platinum member, no attention given. No towel or tissue provided.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

The made us waiting and held our passports and boarding pass making us miss our flights

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Should have had business class line in immigration. Food quality suboptimal

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

In never flown this flight, because my flight coning from Barcelona was delayed.

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

I’m glad the bus waited for me to connect me to my next flight since we were delayed. Flight was good.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

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.

Boarding was unorganised. The flight was very uncomfortable, the temperature was far too high. On requests to lower it nothing changed.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

I liked everything excepct the noise of the engine inside de airplane was a little bite higher.

Rushed due to connecting Lufthansa flight delay Seating very tight and uncomfortable with poor leg room Long lines for rest room

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

Cancelled flight minutes before boarding. Rescheduled flight was two days later

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

No longer a premium carrier and no better than the low cost .

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

The flight was severely delayed. The check in desk was rude.

The flight was several times changed. That was inconvenient, to sah the least.

Boarding is not controlled as groups called was not enforced
