If you wish to request availability for a specific flight, please state the date and origin/departure airport codes, not just the flight number.

Please also restrict requests to BA/oneworld flights - flights for other airlines may be removed to avoid cluttering the thread and taking it away from BAEC.

As of 15 Oct 2014 no longer displays flight availability.

Fare class availability can be queried in various ways*:

        What do the codes mean?
        Suppose we have a result as F1 A0 J9 C7 D0 RC IC W9 E9 T4 Y9 BC HC ...

        This means:
        There is 1 seat in the F bucket for sale
        There are 0 seats in the A and D bucket for sale, but you can join the waitlist in case seats get released later.
        There are at least 9 seats in the J, W, E and Y buckets.
        The R, I, B and H buckets are closed to waitlisting.

        There are two important things to note about how to interpret these numbers that many people don't understand as it is very counter intuitive:
        1) There is NO direct relation to the actual number of seats available on the specific flight. They only mean that the airline is willing to sell this many seats on that specific flight. The airline may intend to oversell seats or withhold seats from sale for many reasons.

        2) In the example above, the results show W9 E9 T4 (which are all WT+ buckets). This does not mean that there are 9+9+4=22 seats for sale. Interpret these numbers as "there are at least 9 seats for sale in WT+". There could really be anywhere between 9 and 22 seats for sale - we just can't tell from the numbers the system gives us. Therefore, the conservative approach of assuming that there are at least 9 seats for sale is usually the best one.

        What does the "C" mean?
        Closed to waitlisting.
        In the example above we have RC, IC, BC and HC. This is different to A0 and D0: The A and D buckets are "full" but you can apply to join their waitlists (if your fare permits waitlisting). With R, I, B and H you cannot even request a seat.

        The carrier will determine how to confirm your seat if it wishes. Sometimes this may happen immediately, other times only a few minutes before the flight's departure. The order of the waitlist is determined by the carrier privately, but your Executive Club status will push you towards the front of the queue. Many cheap fares do not allow waitlisting.

        Differences for non-BA airlines
        • Some carriers (those using Sabre such as AA) only show a maximum of 7 available seats (not 9). Others only show a maximum of 5.
        • Some carriers use "L" instead of "0" (e.g., CL DL YL) to indicate you may waitlist for the seat. This tends to happen when the entire flight is on a list basis.
