Availability on SEA-TPE during your timeframe is spottier (found an option for Mar 31 to Apr 3) than availability on SEA-ICN. There are a number of dates with availability on SEA-ICN in late March (see below). This is the last day to book the SEA-ICN awards (SEA-TPE is an ongoing D1 award sale and will likely continue past today).

Delta's AI must be tracking my IP address, as my return is almost double the miles for this "flash sale". Same results using both Safari and Chrome.
