Deals Verification - Liệt Kê Deal Tiềm Năng

Purpose

Stop wasting 30 minutes searching expired promo codes on Google. This skill leverages AI knowledge of airline promotional patterns, credit card partnerships, and seasonal deals to compile a curated list of potential savings, each tagged with a confidence level.

Critical Disclaimer

⚠️ MANDATORY DISCLAIMER (must appear in every output):

All deals listed are based on AI knowledge of airline programs and promotional patterns. They have NOT been verified through live booking APIs. Always test at checkout before relying on any code. Expiry dates and conditions may have changed since AI's training data.

Input Required

• airlines[] from flight-search results
• route (origin → destination)
• travel_dates
• booking_type (personal/corporate)
• loyalty_programs[] from profile
• payment_methods (credit cards available)

Execution Steps

Step 1: Categorize Deal Sources

Search knowledge across these categories (ordered by reliability):

Category A: Airline Official Programs (High confidence)

• Airline's own sales (e.g., VietJet "Vé 0 đồng", AirAsia "Big Sale")
• 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:

1. Does it apply to this route?
2. Does it apply to these travel_dates?
3. Does it apply to this fare_class?
4. Is the booking_window still open?
5. Are there minimum_spend requirements?
