What we can expect? Soon we will have to travel standing on the hallway. Let me be fair, I had worse experiences with Ryanair.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

Delayed and changed Multiple times after booking necessitating many. Travel changes ; a bit of an issue

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The plane was late (as was my flight out from Birmingham the day before)

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Did not fly to Houston as original flight was cancelled.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Better consideration for families traveling with a disabled person. They insisted each person hold their own boarding pass on their own devices and gave us a hard time accepting eight boarding passes on a single device.

Two of my four flights had issues with toilets either NOT fully operational or completely out of order. Boarding was a joke because they have NOT established who is running the show. In the end, she did a terrible job. The seats 💺 were loose goose and the drinks and snacks were limiting in choices. Also, following Alitalia as an inspiration was strange since they went out of business.

We had a 3 hour delay and then a long taxi to take off. It would have been helpful for the pilot to have communicated more about what was going on. There was no A/C during the wait, and the cabin must have been more than 85 to 90 degrees. The crew gave water to the people in the front but by the time they go to the back of the plane they stopped giving out water. Eventually I went back and asked for some in the rear of the plane (for a second time). The food was close to inedible. I thought on an Italian flight that the pasta would be better than the chick, but honestly, a Swanson's TV dinner would have been better. I had a bite or two to keep my blood sugar up, but basically I couldn't eat it.

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

Terrible. They canceled 2 flights and then sent everyone by BUS from Rome. They should make amends by offering some sort of compensation.

We ordered a gluten free meal and never got it!

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

Seats weren’t comfortable. Both of our seat backs were either almost straight vertical or laying back into the laps of the people behind us, which is a weird angle to try to get some sleep even on a plane. No in between. Also, neither seat would spring forward like they should.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

The space is tight. Either you sit straight up the whole time, but the minute you relax, your knees hit the back of the seat in front of you. My seat would not recline so I was quite uncomfortable. Didn’t use my tray table bc it was stained and sticky and nasty. I was also seating in one of the last rows and one crew member and people going to the bathroom kept hitting my elbow resting on the armrest.

Flight was delayed for 2h. Announcements were poor and I was given 1 biscuit and a bottle of water as consolation. Not happy.

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

The crew’s professionalism was top notch and the food and drinks available were excellent. I only ask that we get the refurbished 777’s on the London to Bermuda route that I had for the London to Singapore leg. The updated infotainment system is much better than the older version

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.
