I dont know if your issue is sorted but ive just booked online ok .

still coming up with that 'singe seat ' message....

all seats showing as available too!!

I got the same message , so i chose a seat at the end of a row , and it worked .................try that and hope it works (cant believe we are having issues with something where the empty seats far outnumber the occupied ones

)

done it, didnt get the seats i wanted, basically had to randomly pick seats and hope for the best! really is poor.

chose my season ticket seats but not got them, but if you have your season card you can have the seats says on website

Got mine now- I Didn’t have the single seat issue thing
