Even in economy, Y and T cabins can have very different refund fees. RBD (Reservation Booking Designator) determines fare, miles and flexibility. Here's what the letters mean.
Besides flight and seat numbers, your boarding pass shows a letter (Y, M, B, H, T...)—the RBD (Reservation Booking Designator). It doesn't mark your physical cabin; it sets fare discount, mileage accrual and refund/change rules.
Common Codes
- ✓F/A: First class (F full fare, A discounted)
- ✓J/C/D: Business (J full fare, C/D discounted)
- ✓Y: full-fare economy, most flexible, highest mileage
- ✓M/B/H: higher-discount economy with relatively lenient rules
- ✓Q/L/T/E/K etc.: mid-to-low discount economy with more restrictions and higher fees
Why It Matters
Two economy passengers can differ sharply: a Y ticket may refund free while a T discount ticket incurs high fees or is non-refundable. Check the cabin code in order details and compare refund rules before booking to avoid surprises.
