Price go up!! Bad experience.
Price goes up without clear explanation adding taxes & feeds as you click through. Shameful. Better to just use Booking.com or fly China Airlines… Update: There was some Black Friday promo that wasted over an hour of my time. Says “one-way from 5,500 Yen”. Later, after wadting your time, you must buy a round-trip ticket. My friend had the same experience. And the return prices are much higher than usual it seems. Update 2: Got email spam about duty free discount. Sad.
