According to that, international travel in the classes R, T and L is not refundable. Which is funny, because when doing a test booking for the future on the same route as a flex economy, AF shows e.g. fare code RKX57RMZ which would indicate class R (unless the fare structure have changed again since 2020). Are fare classes country of booking dependant as well? Or maybe their page is just not updated.

The fare basis have a different structure, example: GS50OBLG

- First letter is the booking class (G here)

- Second letter is the season:
S = valid all year round
L = Low Season
H = High Season
There might be the usual K and J as well for shoulder season etc. I have not found any yet.

- Then there is a figure that codes the week days validity
1 = midweek
2 = week-end
5 = any day (used for Europe it seems)
0 = any day (used for long haul perhaps?)

- then one character for advanced purchase requirement
0 = no advanced purchase (instant purchase fare type)
6 = 15 days (at least for Europe)
X = 60 days
2 = 3 days
4 = 7 days

- The next letter is the minimum stay requirement:
O = minimum 3 nights or Saturday night at destination for European flights
A = no minimum stay (same day round trip possible)
B = one way (note that it might sometimes be cheaper to buy 2 one ways than a "A" return)
I = minimum 3 nights or Saturday night for Long Haul flights
W = 7 days minimum
U = U=TRAVEL FROM INBOUND TRANSATLANTIC SECTOR MUST COMMENCE NO
EARLIER THAN 6 DAYS AFTER ARRIVAL AT TURNAROUND
OR - TRAVEL FROM INBOUND TRANSATLANTIC SECTOR MUST
COMMENCE NO EARLIER THAN THE FIRST SUN AFTER ARRIVAL
AT TURNAROUND.


- The next letter is the flexibility
A = no flexibility at all
B = changeable for a fee, non refundable (70 EUR fee for European fares)
C = changeable for a fee, refundable for a fee (only long haul)
E = full flex, no fee for refund or changes (European and long haul)
M = changeable for a fee, non refundable; shorter maximum stay (300 EUR and 3 months for discounted business class)

- The last 2 digits is for the brand type
LG = Light (no checked bag economy class) Europe
LB = Light fares long haul
ST = Standard (one checked bag economy class)
FX = Flex (one checked bag economy class)
NB = No Brand (which means business class for European flights)
