Taken HKG-TPE-HKG, o/b 29 Nov, i/b 1 Dec respectively for a leisure trip with my girlfriend. For the o/b flight, it was a bit inconvenient due to configuration of MD-90. Seats and legroom were not wide enough. Moreover, the headlamp on my girlfriend's seat was out of order, so it was on the entire journey for 1.5 hours from HKG-TPE. Convenience is much better on the i/b flight as it was an A321. Flight meals on both journeys were excellent. I was mostly impressed by the perfect landing for i/b flight as it was raining heavily at Hong Kong on that day. The only demerit was no individual in-flight entertainment on both flights
