Leaving early was wonderful your seats are for a small person

I had excellent experienced flying with Cebu Pacific on my domestic flight. However, no food and beverage serve might be due to short travel time of 40 minutes.

Your check in lines were terrible everything else was great!

Bags lost for the second time. Will not fly with Cebu Pacific again.

Delays on the tarmac, uncomfortable even after paying extra for premium seats. Bags lost in transit, no compensation provided

Delay and flowing long wait for leaving the aircraft after landing. IDK, if it's worth.

Terrible, I will never ever ever attempt to fly on Cebu Pacific. I understand that it’s a cheap flight option but they take cheap experience to the next level.

The flight was delayed for 3 hours and I missed my transit flight.

Was denied early boarding for a hot seat row 1C. I asked gate attendant why I couldn’t I board as I paid extra for that seat and it’s privileges that come from purchasing it. and she said no that Cebu Pacific does not allow it. When I boarded plane finally I had nowhere to put my bag as the seats behind me had taken my overhead area. The flight attendant said that the gate attendant was wrong. I fly a lot in the philippines and to Japan and now I have no choice but to fly with Air Asia. At least they board with zones and allow rows 1-3 to board early.

I am 74 hrs old and I appreciate walking on the ramp instead of using the stairs. Too bad they didn’t have that on the return.

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

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.

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.

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.

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

It would have been nice if I could have actually travelled to Perth. I injured my back and was unable to fly. Scoot refused to change my ticket saying it was not flexible. However I purchased the ticket through MyTrip and it was flexible. MyTrip wanted to charge me an extra $271 to change to a ticket that was only listed as $217. Never again will I fly Scoot or book through MyTrip

Me and my Partner were in seats 6A and 6B. (Which we paid a premium for). Unfortunately the person is seat 6C was large and because of his size my Partner was squashed to the point of discomfort and unable to sit properly. We requested to be moved to some empty seats and two hours into the flight the crew moved us. Perhaps it’s time airlines began checking passenger sizes to ensure they don’t encroach into fellow passengers seating space!

Delayed 50 mins. Check in was excellent, boarding was good, everything else was OK and perfectly acceptable for a budget airline. Price was excellent. I noticed this airline had two other flights to our destination cancelled so not very reliable.

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

The issue was a 4 hour delay to takeoff with very sketchy information provided about the available of the flights delay. Passengers were not informed of gate changes and how long the delay might be. It ended with a late night 2 hour drive to our home which was not ideal for elderly people.

Flight was fine with boarding starting a few minutes early. Not a fan of the crew pushing political messaging regarding indigenous naming of Brisbane city… really pushed it like I haven’t heard on Jetstar before.

Flight was delayed more than 1.5 hours. Gate changed multiple times

no announcement about why we where delayed which is very poor

It is what it is - nothing more, nothing less. No entertainment onboard but one kinda knows that when buying a ticket on a no frills airline. I choose Jetstar only because of price.

Plane was delayed both on arrival to Sydney and departure. We boarded the plane while it was in the process of being refuelled, which I am certain is against CASA regulations. Comfort for anyone over 6 foot is non existent.

Online checkin was a nightmare. They kept popping me into Chinese language site which I can't understand.

The flight take-off was delayed which was fine but the staff seemed pretty over their jobs. The seats are very uncomfortable and the food was pretty average. Overall is was okay.

Freezing onboard and staff refused to give me hot water “because we were landing soon”. The plane arrived at the gate an hour late. And there’s an air leak in one of the bathrooms. Very scary noise.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

2 delayed flights - hotel layover in a different country- lost baggage.

You get what you pay for. It’s functional and gets you from point A to B in good comfort. However, food options are limited and cash only, Crew is a hit and miss .. they get your attention if you reach out.

Good leg room ... air conditioning was a bit warm don't Book row 8 ... no windows

They got to the terminal late, with no one on the arriving flight, boarded us late, and left us sitting there for 2 hours before they got us off the ground. They knew they were going to be late, yet they never got an updated flight plan from their head office until long after the flight was supposed to leave. They could have cut the delay in half, of at least let us stay in the terminal. Really just horrible planning.

The worst kind of budget airline. To be honest....the plane was not that bad. Would have been good to have some food choices and some water. What was by far the worse is the passengers/customers that this airline attracts. Coughing and spluttering all over one another with no masks. Just disgusting. Pay for a better carrier and get a better class of passenger.

Flying from Koh Samui to Ha Noi with a layover in Bangkok. Vietjet cancelled flight. When I went to the counter they told me to call from r information. I asked for the number and they said they couldn’t give it to me. Be a little taken back I asked him to repeat that while I was recording on my iPhone. He told me that was unacceptable and called the airport police. I deleted the video but had to deal with a big hassle. Then booked with a different airline. Vietjet wouldn’t refund the ticket. Luckily Chase Sapphire didn’t have a problem with refunding me. Vietjet blows!

Terrible customer service. My last choice to fly now if there is no other options.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

Waited for 1 hour on tarmac because they couldn’t locate a tow truck. Flight was fine once we eventually took off.

Late departure, late arrival, and personal items on laps during takeoff and landing. Departure gate opened on time, but no direction as to whether to board at front or rear of plane based on seat number. Fashionable staff with sunglasses inside the plane and cockpit remained for ten minutes after the boarding complete announcement. For a scheduled 80 minute flight, adjusted to 65 minute as noted on takeoff; the total time on the plane with delays was r more than two hours. No confidence had there been an emergency that anyone would have been able or aware of what to do.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Paid for seats near the window but given seats right at the back, near the toilets. This location was so noisy with the blasts from the aircraft engines blowing beside. Not a nice one 😞.

Some chair in the flight should be maintained, but I think they may not have time to check every seats, since it is high demand in this period.

Our experience was the worst. Over 2 days flight was changed and delayed 4 times. Not impressed

Flight was okay. Seats were a bit cramped and not that comfortable, especially for a 7-hour flight, but you get what you pay for. Food has to be bought also so plan ahead. But if you can tolerate it then it’s not a bad deal! Staff are nice too.
