under the clocks, now that the children have had their fun

....the system only allows a one digit numeral (0 to 9) to indicate availability under each fare type available for sale on that flight.
Airlines, because of commercial sensitivity, don't want to broadcast to their competitors exactly how many seats there are available for sale. The maximum numbers shown are different for various airlies (as
Wongo asserted, 4 is the TG maximum). Also, where there is a codeshare flight, the codeshare partner will usually only have a maximum of 4.
Thus the "true" number available will greater than or equal to that maximum number (whether 4 or 9) - where it shows for example "A9". Once there are less than the maximum seats avalable, it usually shows the true number of seats.
Whenever you see a U with a number next to it other than 0 on your flight, smile, ring up QF and grab it/them.
Now on that note, it's time for a HP (or Cascade Light, whichever is available in my office fridge

)
