When
You read TWD and need to know what each coupon letter allows you to do.
The statuses
| Letter | Meaning | What you can still do |
|---|---|---|
O | Open for use | Void (same day), refund, revalidate, reissue. |
A | Airport control — the airline's airport system holds it | Changes usually through the airline. |
C | Checked in | Not changeable by the agency. |
L | Lifted / boarded | Travelled. |
F | Flown / used | Nothing — it is used. |
E | Exchanged / reissued | Look at the new ticket. |
R | Refunded | Done. |
V | Void | Done; the sale was cancelled. |
S | Suspended | Airline investigation — ask the airline. |
I | Irregular operations | Airline disruption handling. |
U | Unavailable | Ask the airline. |
P | Printed | Converted to paper. |
G | Converted to FIM | Airline used a flight interruption manifest. |
T | Paper ticket | |

Traps
- Only open (
O) coupons can be voided, refunded or exchanged by the agency. - A partly flown ticket (first coupon
F, returnO) can still be refunded or changed for the unused part — see Partial refund — the refund record, used coupons, taxes and penalty.
