All budget airlines understandably have their ways to cut costs, but this one has gone beyond all human necessity, let alone human decency, and ventured into the acts of fleecing passengers of as much extra money as possible with hidden rules and charging extra for services that are supposed to be bare basics for a flight, such as having a seat in the plane or a cup of water for a four-hour flight. You would start noticing the unusual practice of demanding additional payment for normal online check-in - extra money if you would like to check in even for a standard seat - so really, their air ticket price, which you have paid in full, does not include a seat. So you are supposed to be standing in the plane if you don't pay extra? Or has the airline been requesting duplicate payments from passengers for the same seats they have already paid for? Then you find out that they have shrunk the hand luggage to a pitiful 40*25*20 - but even if you comply with this requirement, at the airport they will suddenly bring out a tiny metal scale (which appears much smaller than the already pitiful measurement), and insist that your hand luggage will only be allowed if you can fit it in that tiny scale. If you ask them for a ruler to prove the scale is correct, they will definitely refuse, as they did to me repeatedly. You will then have to pay an astronomical amount of additional money to be allowed to take your pitiful and already compliant tiny luggage. And they still haven't explained to me why they refused to bring out a ruler to check their scale or my luggage. Then they tell you that not only do they not provide food during the four-hour flight (through lunchtime), they do not provide water either. And they actively stop you from bringing your own water onboard. Why? You guessed right - they want to sell you water onboard at an obscene premium. So for a four-hour flight going through lunchtime where the passengers are inevitably confined within their cabin and there is no way to get out, no food even for those with low blood-sugar and no water for those feeling ill? That is a serious breach of basic health and safety rules and standards. That's also a breach of basic duty of care, like selling you a knife without a handle and a car without brakes (it's a product technically, but you can't use it without seriously injuring yourself so it's not a proper product meeting basic requirements and is a breach of the law). In conclusion, you will inevitably pay more, or much more, than shown in the air ticket if you fly with this airline, but still get treated like an idiot. You will find that the price you end up paying could probably get you a business class ticket with a decent airline anyway

Very bad experience with H.K express. They will push you to pay even on carry-on baggage which meet size and weight requirement with any excuse. And you will get no address by the customer service if you have complaint case.

Applied Fraud at HK Express Be careful and don't book this airlines. They charge you extra for check in baggage and then they claim that it is cheaper when you pay via their website. The fraud is that their website is not working. When I told this the staff by checking in she knew it. When I complained at the customer service they didn't do anything. The reason is that they charge double the amount if you check in at the check in counter. So they are not interested in a working website. They are charging you double the fee! It is unbelievable. I don't understand why the Hong Kong government is not investigating this airline. Anyway I will never ever book this horrible airline.

HK Express rescheduled its flight UO566 from HK to Nha Trang on April 29, 2019, from the original 15:50 to 08:05. As I have a same-day connection, I cannot take the flight. The airline gave me two rebooking options without fees one week before or after April 29, 2019, for the same route or a different route. Since the period of my travel has been fixed and they don't have flights to Nha Trang every day, I had to change to a BKK flight. First, I was told that a change to a flight to a different country was not possible. I told them that there was no such restriction on the message notifying me of the change. After some checking, they said it was OK. However, the ticket price was higher, since it must be changed at the call center where ticket prices are generally higher than on their website. The BKK ticket ended up more expensive than their competitors. This is clearly unfair. The change was forced on me, not my choice. Think twice if you want to tak HK Express. For me, this is my last ticket with HK Express.
