Long-time lurker, first time poster here, so please excuse my selfishness in noting down my random thoughts and ramblings here.
I seem to have developed a morbid curiosity in trying to decipher the QFF SC earn rates from JL domestic flights, so hopefully I can add some helpful (albeit mostly anecdotal) info here. I do agree with elanshin it's super confusing.
The last thread I read on this should be:
Crediting JAL Domestic flights to QFF
I'll quickly note that the
JAL domestic fare range changed around Apr/May 2023 - the most relevant fare type names for us would likely be Flex, Saver, Special Saver and Round Trip.
I'll also note that whilst I've looked at the JAL Japan Explorer Pass offering in the past, I've never used it and instead have booked from
JAL's (Japan) main page.
Took two flights as follows (separate PNRs):
| Route | Fare Type | Class | Fare Type (from the Boarding Information Slip) | Flight date | Credited date |
|---|
| ITM to CTS | Special Saver | Economy | QLCSIEAB | Thu 01 Jun | Mon 05 Jun |
| CTS to HND | Special Saver | Class J | XLCSIEAB | Sun 04 Jun | Mon 12 Jun |
Both flights earnt 325 QFF Pts and 10 SCs each, so as HirafuHeartAttack already mentioned, it's not a lot.
One thing I did notice is that the JAL domestic booking system appears to be quite different interface-wise from the international booking system - and the Explorer Pass uses the international one.
The international one at least makes it clear what the fare/booking class is when you've selected the flight(s).
Based on this, I initially (stupidly) thought that the earn rate for QFF Pts and SCs would thus be based on the "All other flights" section of the
QFF airline partner earn table for JAL, and as such most Explorer Pass fares would earn at the Discount Economy rate (170 pts/10 SCs). But based on HirafuHeartAttack's two flights, this assumption of mine is incorrect.
It does make me wonder why one of HirafuHeartAttack's flights earnt zilch, so I'm curious as to what the fare type from the boarding info slip and the booking class would be for those two.
So I'm thinking the QFF earn from JL domestic starts to look like this, but I could very well be wrong (I'm going to assume substituting "Saver" for any discounted fare like the Explorer Pass would still work/make sense):
| JL Fare Type | JL Class | QF Booking Class Category | QFF Earn Category | QFF Earnt (one way, HND-CTS) |
|---|
| Saver* | Economy | Y (Discount Economy) | Economy | 325 Pt + 10 SC |
| Saver* | Class J | J (Discount Economy plus Premium Surcharge) | Economy | 325 Pt + 10 SC |
| Saver* | First Class | F (Discount Economy plus First Surcharge) | Flexible Economy | 650 Pt + 20 SC |
| Flex | Economy | Y (Economy) | Flexible Economy | 650 Pt + 20 SC |
| Flex | Class J | J (Economy plus Premium Surcharge) | Premium Economy | 715 Pt + 20 SC |
| Flex | First Class | F (Economy plus First Surcharge) | First | 975 Pt + 60 SC |
Flex fares seem to be roughly double their Saver equivalents but it's probably not worth the extra cost for the extra pts + SCs.
I've got a Round-Trip Saver fare coming up soon so we'll see how that goes, but hoping at least that would earn at the Economy rate for both legs. I'll be sure to hang onto the boarding info slips.
Side note: I've also recently learnt that QFF Classic Reward redemptions for JL domestic flights can be managed via the international booking system, not the domestic one.
