When
You want to see whether cheaper fares exist on the booked flights before deciding — without changing the booking.
Steps
| # | Entry | What it does | Why |
|---|---|---|---|
| 1 | FXA | Lists lower available fares for the itinerary; nothing is rebooked. | Safe comparison. |
| 2 | FXA/LI · FXA/LO · FXA/LA | A list of lower available fares · the lowest plus others (maybe not available) · only the lowest available. | Choose the view. |
| 3 | FXA/KC · FXA/KW | Lowest in a cabin · economy and premium economy. | Stay in a cabin. |
| 4 | FXL | The lowest possible fare and whether seats are available. | The floor price. |
| 5 | FXU2 | Rebooks to the fare on line 2 and creates a TST (needs names). | Accept it. |
| 6 | FXZ2 | Rebooks to line 2 without a TST. | Accept, price later. |
Check it worked
The list shows each lower fare with the classes it needs; after FXU/FXZ, RTA shows the new
classes.
Traps
- A lower fare shown with
/LOor byFXLmay have no seats — onlyFXA(default) and/LAshow available ones. - Lower fares usually have stricter rules; compare
FQNbefore switching.
