Execution Steps
Step 1: Categorize Deal Sources
Search knowledge across these categories (ordered by reliability):
Category A: Airline Official Programs (High confidence)

- Early bird pricing (usually 60-90 days ahead)
- Airline birthday/anniversary sales (recurring dates)
- Route launch promotions
- Companion fares for loyalty members
Category B: Card & Partner Deals (Medium confidence)
- Credit card airline partners (e.g., Techcombank-VN Airlines)
- Bank points redemption programs
- Corporate partner rates
- Travel aggregator exclusive codes
Category C: Public Coupon Codes (Low confidence)
- Aggregator coupon sites (RetailMeNot, etc.)
- Social media flash codes
- Email newsletter exclusive codes
- Influencer/affiliate codes
Step 2: Match Deals to Route and Dates
For each potential deal, verify applicability:
- Does it apply to this
route?

- Is the
booking_window still open?
- Are there
minimum_spend requirements?
