Flew HK airlines a month ago. Took four flights in total as part of the trip. Two long haul and two short hauls.
The long haul planes were old, but it was fantastic. There were no in-flight entertainment units on the backs of seats. Instead, they gave out iPads to everyone. Seats were comfy with good legroom and the ability to recline more than any plane in recent memory.
The short haul flights were more modern with in flight entertainment and seats comparable to more modern aircraft.
Service on all flights was top notch, friendly and efficient. All four flights left right on schedule.
