Hi,

Was looking through this website http://www.flyaow.com/classamex.htm and looked at the availability for QF179 MEL-NRT for Nov 4 and am just wondering what all these numbers mean?

Cabin class: J9 C9 D9 I9 U2 Y9 B9 H9 K9 M9 L9 V9 S9 O9

Thanks

Each letter is a "fare bucket" "seat bucket" or "seat class".

The number is how many seats are left in that bucket. Most of the time it is somenumber between 0 (no seats, or ITN can't see any availabilty) and 9 (meaning at least 9 seats are available).

Sometimes they correspond to actual individual seats, sometimes not. (ie J3 D3 might mean there are only 3 seats available, and they are happy to sell them as full fare or discounted fares, or there might be 6 seats left. We'll never know!)

For QF A F Z are first class buckets (Z being the award/upgrade seats)
J C D I U are business class buckets (U being the award/upgrade seats)
the rest are normally economy class seats (X or T being award/upgrade seats).

On BA, W, T and P are world traveller plus seats.

Basically, if you see all 9s then there is room on the plane. If you see all 0s then it's full. If you are trying to book a particular class (N/O red-e-deal or similar) then it can be useful. If you are hoping for a ODU then D4 Y0 would be good (if you are a WP or higher), J9 D9 U4 would be even better.

The letters refer to the fare basis, where P, F, A, Z are first class fare types, J, D, C, I and U are business class fare types, and all the others are economy class fare types (except for BA where they also have a premium economy called World Traveler Plus which is W and R I think).

The number is a range from 0 to 9, reflecting the number of seats available for sale on that particular sector. The number is the minimum number of seats for sale in that fare class. So a 9 means there are at least 9 seats available for sale.

Some airlines use 9 as the highest number they show, others use 7 (like AA) or sometime 4 (often for codeshare flights). But these just mean there are at least 7 (or 4) seats available.
