The bathrooms were stinky dirty and the the floor was sticky. On one flight I had the worst food option I have ever had on an overseas flight.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

No control at all at the gate , passengers were not cuing up, , some were very loud , no action taken by the attendants . It looked more like a heard of animals then humans boarding a plane .

Seats paid for in advance. Seat assignments changed by kayak 3rd party. Seats then changed again by Turkish airlines at the gate. Family seated on opposite sides of the plane yet money taken for seat assignments that were not honored.

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

We had requested a wheel chair assist for my husband who has Parkinson’s. The first seat we came to we got off the plane was staffed by 3 men-one was on his cell phone, one was sleeping and the fellow we spoke with was rude and seemed as if he didn’t care that we had a plane to catch in one hour. A person with a wheel chair came and took us to the center area for wheelchairs. Here we waited for 20-25 minutes while our flight went to “boarding.” Finally a woman came with a cart and we zipped through the airport.

Cancelled with no notification and no assistance from ground staff re options or rebooking, where to stay or how we could get home to LHR.

The crew checked the immigration laws very quickly for Russian citizenship and confirmed our FVTF for Singapore for 96 hrs. Thank you.

They have adopted a crazy "no paper boarding passes at all cost policy". We spent half an our at the checkin stall – my elderly mother and her grandchildren were flying. She had no phone reception for some reason (besides being an inexperienced smartphone user), the kids had dumbphones, And they still won't issue a paper boarding pass. We had to do a lengthy dance with getting the boarding pass SMS on my phone and transferring them to her phone via WiFi. This was horrible, honestly. I can't imagine how they could manage it without me being there. Trees (and airline profits) should be less important than people.

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

It was very relaxing and staff were very quick to attend to any requests.

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

Unfortunately the flight was cancelled so I never got to go

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Early arrival. Good boarding. Deplaning this flight is very slow both coming and going. Baggage arrived quickly for Pearson

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

3 hours delay ,we changed plane after boarding and waiting inside

Apart from the staff at the airport who were amazing the rest of the experience with scoot was disgusting a very basic flight packed and uncomfortable no consideration to a disabled traveller. And even worse from Singapore to Vienna. All about the money. Not even a complementary coffee or juice. From the airline. The staff at the airport didn't look at me as been disabled and no help not even a wheelchair was offered. The food on the plane was cheap and tasteless and expensive no entertainment on plane and WiFi which had to be paid for was intermittent at best.

Uncoordinated boarding, seat comfort is terrible, even toilet is so small that overweight people wouldn't fit in. Baggage scam with additional fees. Stay away from this airline.

Forthright communication to the customers regarding services offered and any fees involved.

Scoot is a no frills budget airline. Do not expect a legacy airline experience.

I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.

Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.

Food & lower the prices. Look at Air Asia food look better & affordable

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.
