2026 ‘Buy One Get One from NT$5,588 + 15K Asia Miles’ Hong Kong deal still exists but with stricter conditions — BOGO requires both passengers to share PNR (no dual-account), 15K miles credit requires Asia Miles enrollment 14 days pre-booking, and ‘from NT$5,588’ applies only to Mon-Tue 06:00-08:00 departures.
📍 Booked Cathay HK BOGO with friend’s separate booking Both of us tried for the BOGO at NT$ 5,588 each. Discovered the BOGO requires shared PNR (one booking, two passengers), not two separate bookings. My friend’s separate booking forfeited the 15K miles bonus and the BOGO discount = paid full NT$ 8,400 each. Always verify shared-PNR vs separate-booking rules before assuming BOGO applies to multi-passenger trips.

My experience is one data point. I’ve tried to back things up with research and real When this strategy doesn’t help you: If you have fixed travel dates and no flexibility on departure city, most of the optimization techniques here don’t apply — your options are limited to what’s available. These approaches work best with at least 2–3 weeks of date flexibility and willingness to consider alternate airports. For fixed itineraries, the main tool you have is booking early.
