Thai Airways (TG) offers the most consistent pricing at $628–$789 round-trip from JFK for economy, while Delta (DL) charges $820–$1,045 for identical routing with no checked bags included.

Delta’s lowest fares for March 2026 appeared on February 14 (after the Super Bowl), while Thai Airways’ best deals were available January 28–30.

Watch Out For: Delta’s Hidden Baggage Fees

Delta charges $100 for the first checked bag on all New York–Thailand routes, not shown in the initial search results. I discovered this at EWR airport in March 2025 when I was charged $100 for a single 20kg bag after booking a $820 flight. Thai Airways includes one 23kg bag in base fares—saving $100 per person. Always check the "baggage allowance" tab before booking on Delta.

Flights depart from JFK (not EWR or LGA) and arrive at Bangkok’s Suvarnabhumi (BKK), 35km from downtown.
