Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Too many people are taking up space in the overhead bins with their extra piece of luggage. Since they cannot fit their backpacks or extra luggage piece under the seat in front of them, they store it in the overheads and thus taking up room for other passengers. It wasn’t only one or two persons; more like 12 or 13 passengers.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

Got to fly my favorite plane, the Boeing 767-400ER, to Milan. The soft blush pink mood lighting during meal service was very beautiful and gorgeous. The service was top-notch, and our flights were on time. I highly recommend Delta.

I am still at the Airport! Delayed Delayed and Delyaed

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

In a 6 hr flight after paying over $700 dllrs of ticket and we still needed to pay for our own food and given ONLY a small glass of water!!! Will not be flying internationally anytime soon with them They are good for very short flights

No food was served on the flight. Boarding desk open two hours before departure. But they recommande to be there three hours before departure !! So we where a group waiting 1 hour in Line for nothing …

My flight from Toronto to PDL was one of the worst experiences of my travel history. I paid for an upgrade and did not receive it, and was also charged an exorbitant amount for a 25-inch bag, and when I tried to explain the situation, I was only told the flight was already over capacity. & I had to accept what I could get!, I am a frequent traveler and will not be flying your airline again!. The only thing positive in this entire trip wete the flight attendants, but other than that, everything else was very disappointing!

They charged us 100 Euro per bag on the return leg with no explanation.

Everything was perfect, clean and very nice staff. But the seat was uncomfortable compared to other companies and the food wasnt good

Flight wasn’t full so got to stretch out and sleep.

Boarding was delayed. Then when we queued, it took us to another long line to stand in. Flight had 0 entertainment. Not even a magazine. But they had a free meal and it was good!

You cannot add an additional luggage via the check in. It seems to be an issue with Azore Airline.

The facilities at PDL are absolutely appalling during a 4.5-hour connection. Passengers from multiple flights were crammed into a small area with insufficient seating and only a snack bar. The only bathroom was unisex, with one stall for men and another for women side by side. This is for hundreds of passengers. The connecting aircraft from PDL to JFK was downgraded/switched out to an Economy Class-only configuration without explanation, even though the aircraft with Comfort Class we arrived from FNC on remained at the stand. Those who paid for Comfort Class could not enjoy the better seating or catering. Food and drink aboard was sub-par. I would qualify it as one of our worst travel experiences in years.

The crew was great. The only problem is that electrical outlets were not working in what seems to be a half of the rows on the plane. Considering that passengers are asked not to use power banks, this leaves us out in the blue without any entertainment option.

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.

Kayak let me choose these flights on TAP but then after 2 months, cancelled my flights because they didn't think 90 minutes was enough time for the connection. I notice that neither flight was actually cancelled. Just my reservation. Why let me go through all of that effort to find the right flights for us, only to cancel it from underneath us 2 months later leaving us scrambling to find an alternative?

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Bad. They gave me a voucher for food to use at the airport but didn’t have time since I had to catch the other plane. No refunds and lack of communication

Negative. Food was awful, seat broken, flight was late, baggage lost and damaged

The ground staff did not load my bag onto the plane and despite me watching from the bus that my bag is not being loaded and taken back on the cart to the terminal, I pointed out to the staff and ge laughed upon checking my tag and knowing they made a mistake. Instead of calling the cart back and loading it he said we can’t fo anything and you should file a report upon landing at RAK. I told them my stay there is short and i needed my bag as it had everything I needed but no avail. Even the pilot was informed, staff of the plane was aware but all in don’t care mode. Upon arriving at Marrakech RAK, i filed a report and being told it might come in next flight tomorrow and we don’t provide delivery service, you must come and pick it up. If it doesn’t arrive on time then it will be sent to your home in the US. Unbelievable stress and inconvenience that could have been easily prevented by the ground staff.

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.
