We'll be flying Hong Kong Airlines, a budget airline of Hong Kong (Screw you J-Air and Peach airlines not going to Hong Kong). The picture below is a plane of similar specs (A320, 3-a-breast). I'm personally not expecting too much from the budget airlines, other than walking off that plane alive. I do hope it's a bit more comfortable than American Airlines.
When will I be departing and returning Hong Kong can be seen if you follow my Twitter an Facebook, thanks to MySkyStatus from Lufthansa.
