Not only low cost but also low standards.
Sorry to report that I agree with most of the negative comments here! Their cabin bag policy is from the dark ages, nobody travels without some type of cabin bag, but some of their fare categories preclude cabin bags, my ticket specified a cabin bag, booked through an agency, but their Tokyo checkin adamanyly refused to accept the bag, and insisted I check it in. They are totally inflexible, even if its their mistake, and their attitude at checkin is all about how to make more money!! In addition, having now to check in my bag, I offered them four credit cards (one being HSBC) to pay, each one was declined & they insisted I withdraw cash to pay. I called two of the card companies to ask about the decline, only to be told that they did not decline the transaction. Obviously they prefer cash so as not to pay the CC fees. A passing comment to finish, HK Express is a wholly owned subsidury of Cathay Pacific, an excellent airline but seems they choose to ignore the huge number of negative reviews of their low cost daughter!!
