Pros: "Food & condition"
Cons: "Crew were unfriendly and rude"

Pros: "Everything"
Cons: "Nothing"

Cons: "The Manchester stopover was just a lot of standing in lines. From Manchester to Singapore, the plane was full and my seat mates didn't get up when we needed out. So, we escaped to the back for a while where we were "hushed" by a stewardess. The stewards didn't seem to like it when we were out of our seats, but 12 hours is too long to be stuck in a middle seat."

Pros: "I liked how often the staff walked down the ailes to help. They are very attentive. The entertainment is endless. Seats were standard in economy class, I recommended upgrading for that long of a flight."
Cons: "To my flight specifically, it got adjusted without telling me so I ended up missing my final transfer. I was not given a notification for a flight change. Someone met me at the end of my second flight to tell me I missed my connecting flight. With the adjusted flight Singapore gave me, there was no chance I would have made it. They did purchase a ticket for me on another airline to get to San Francisco in the end."

Pros: "Great value at a great price"
Cons: "N/A"

Pros: "Very comfortable"
Cons: "Drinks would have been better since short flight it’s ok"

Cons: "Took off on time finally got off the plane 45 minutes later than the said arrival time"

Cons: "Boarding was a bit chaotic you could have started loading by blocks of row numbers from the back"

Pros: "Good, fast, logical service crew. Seating was tight but that is logical on a short flight. Everyone was friendly and efficient. Staff seemed happy and very pleasant."

Pros: "The crew are novices, but really try their best. Most of the seats on the flight were empty! Great for lying flat. So that’s why tickets are cheeeeaaap."
Cons: "Everything about this plane is old. And creaky. Very old seats! The fabric is worn down! NOTHING is available to eat and drink. Zero entertainment. And when the plane gets cold, bring your own blanket, or covering. Other passengers have to be a negative. Some have never flown before, some walk up and down when we are all supposed to be seated. The crew do their best to coral everyone, but they’re just unruly. Best to find your own seat, far away."

Cons: "The flight left before scheduled departure time. Many were stranded in Phnom penh. Please issue refunds."

Pros: "Easy check in, nice equipment. Very efficient."

Pros: "More leg room than usual. Seats clean."

Cons: "We should have been allowed to sit near our family (wives). There was empty row but they wanted to charge us to move up. Ridiculous!!"

Pros: "Check in staff was friendly and helpful"
Cons: "Refused to serve me food when I woke up."

Pros: "Absolutely nothing"
Cons: "The flight took forever to land. Pilot said prepare for descent and we stayed in the air for another forty minutes. The air smelled awful. One of the worst flights I’ve ever taken."

Pros: "I was able to purchase extended seat room for a reasonable price."
Cons: "No free drinks or entertainment or anything to help pass the flight time."

Cons: "Staff at check-in counter were not helpful. They were there and they weren't. We were there at the front while two of the counters were ready but didn't call us up. They were chatting with each other instead. We I asked them are they ready to work, she ask me where was I heading. What is the difference?"

Pros: "Comfortable seat in emergency exit row!!"

Pros: "HK Express compensated for delay"
Cons: "Punctuality"

Cons: "Fight was delayed 2 hours"

Cons: "Terrible attitude from the staff"

Cons: "Sat on runway 2 hours and then bags delayed 1 hour"

Cons: "They didn’t offer any thing to drink, complimentary"

Pros: "Price was good and HK to Tokyo times were good"
Cons: "No entertainment on 5 hour flight"

Pros: "Good price to go HK to Tokyo"
Cons: "Flight attendant woke up a baby to tell passenger something and then baby cried for next hour No water unless you pay for it"

Pros: "The crew was very nice, seats comfortable and the airline seemed well run for a discount carrier."

Pros: "Easy flight, nice crew"
Cons: "Budget airline. Have to buy drinks. Space between seats is tight. Spend the money for the seat with more leg room if you are average height or taller"

Cons: "IS THIS A WAY TO RUN AN AIRLINE? WHAT A BLANKING JOKE! People should notify Ralph Nader & PUT in a LAW or a LEGAL INSTRUMENT that MANDATES compensation to “We the People”, the consumers, the citizens, the customers, man. IF a flight leaves 1-15 minutes late = okay BUT IF a flight leaves > than"

Pros: "The web specials for prices"
Cons: "At least provide water to guests."

Cons: "Service from the crew could have been better. This crew was not hospitable and we had to ask multiple times for our requests."

Pros: "I wasn’t able to get the flight and the booking agent never amended this despite 2 weeks of emails and phone calls"
Cons: "Lastminute.com could have answered my emails"

Pros: "Low budget and efficient"

Pros: "Service was fine. Charged 50 usd for 21kg checked baggage. Food and beverage was not complimentary during flight."
Cons: "Fine experience. Stuck next to obese traveler that forced me to lean into the aisle. My bad luck, not the airlines fault."

Pros: "I just want a seat in a high season!!!!!!!!!!"

Pros: "Friendly crew and very organized"
Cons: "Wish we didn’t have to buy water and entertainment lacked for a flight this long."

Cons: "Made me do a ticket change because I used the first initial and not the full name for my middle name. Been flying 30 years and this is the first time I have had a problem. Won't take these bargain airlines again. It was my first time taking one. Same with my 6 year old's ticket as well."

Pros: "Everything"
Cons: "Nothiing"

Pros: "Price was good."
Cons: "Never boarded the plane! I was not notified that luggage check-in closed 1 prior to departure; who knew it would take luggage more than an hour to reach the plane... I checked-in already and was only a couple minutes past the cut-off; they wouldn’t check my luggage in. Instead of offering some solutions or let me pay extra for checking at the gate, I was told my flight was closed, I would have to re-book at full price. I was there before the posted boarding time with time to spare. To top it off, I received a phone call from them asking if I was on board the plane.. online chat with customer service, not helpful either, thenperson I was chatting with just ended the chat after telling me 1 minute past they went check in."

Cons: "Although it was one e-ticket, I was surprised that HK express could not forward my luggage to my final destination. This almost caused me to miss my connection and caused me to pay twice for my extra luggage (which accumulated to a significant amount)"

Pros: "Easy boarding, and slept the flight."
Cons: "It was the hidden prices after booking that ticked me off. Charged for seat after paying airfare, charged for any checked baggage, no in flight service without charge, and you arrive so late to HK you have to Bus or Taxi in. Not worth it."

Pros: "It was a short flight."
Cons: "Tried to save by booking a different carrier. When it can time to check in... I was charged for my seat, charged for a carry-on weighing more than 7kg and forced to check, chose not to pay for a meal, pay for a drink... so many hidden fees. Ended up not saving at all. No savings, no miles, no perks. Will always use an aliance (UA, Asiana, etc) or SkyTeam (Delta, Korean Air) from now on. I at least get my money’s worth."

Pros: "I love when they have great deals on airfare. The late night flight works well for me."
Cons: "Wish the air cooler was stronger and that water was served during the trip."

Cons: "Budge airline, uncomfortable seats"

Pros: "On time"

Pros: "Price is good"
Cons: "No entertainment, no water"

Pros: "I'm glad it was only a three hour flight"
Cons: "I connected from a Cathay Dragon flight onto an HK Express flight to Jeju. At the transfer desk, the ground agent told me I would have to leave and reenter the restricted area despite having no checked luggage. Knowing it can't be right, I checked in on my phone and went through the normal transfer process in HKIA. It was a 0215 flight from the midfield concourse. The last automated passenger carrier left at 0100. After which, passengers would have to rely on sporadic bus services. The captain announced 'cabin crew, prepare for landing' 45 minutes before landing. That woke everyone up and it was not ideal. All the flights I have been on announced landing when the plane was at base leg."

Pros: "Cheap service out of Hong Kong"
Cons: "Lack of seat pitch"

Cons: "Due to their mistkes with connections and communication I never made it on my flight therefor the specific indicators way be inaccurate but I would say an overall terrible experience."

Pros: "The airport had an emergency shut down and we didn’t get notification about it. When we showed up in airport, the only accommodation was 250 Thai bhat Burger King vouchers that it’s not even enough to buy a drink after getting a burger."

Pros: "On time departure and arrival, had priority boarding and check-in, you get what you pay for."

Pros: "Great job"
Cons: "Small seats"

Pros: "Professional staff"
Cons: "n/a"

Pros: "Comfort"
Cons: "I did not like that there was no food or snacks given for the flight. Also did not like I had to pay for a drink of water."

Pros: "Quick flight between HK & DaNang on time both directions. Convenient flight schedule. Smooth flight. Crew was friendly."
Cons: "Had to purchase food, beverages but wasn’t really necessary due to short duration of flight"

Pros: "Flight departed on tme and arrived on time"
Cons: "None"

Cons: "got sick from food"

Cons: "Could not contact service team even Hong Kong office. They just sent email to let us know the delay, but nothing at all"

Cons: "Seats were very very uncomfortable"

Pros: "Cheap but on time"
Cons: "Too much promotion message"

Pros: "We landed safely and the crew were polite"
Cons: "Late on the way to Da Nang and very late on the way back (flight back to HK was a Hong Kong Express plane). Budget airlines are just not worth it at HKIA - your flights lands and takes off so far from the terminal, you are transferred by bus! No in flight entertainment- although not an issue on such a short flight."

Pros: "It was cheap"
Cons: "Everything about it was not good and I will never fly them again"

Pros: "Nothing"
Cons: "The flights was canceled till now no refund"
