Hello I am looking for advice please.

Flight:
DOH to LHR
Cabin class: World Traveller Plus
Aircraft type: 777
Flight number: BA0126

I upgraded to a premium economy seat for my flight hoping for as much leg room as possible. I was disappointed to see that the seats I would have chosen to purchase have already been reserved.

Is there any point in me paying for 24AB (no one behind and an aisle seat for my 6ft 2 partner even though it’s in front of the toilet)?

Current reserved seats by others: 20A-K, 21A, 21JK, 24JK.

At this point I’m tempted to save my £90 and just hope that we get one aisle seat. Thank you
