"British Airways also tends to release more award seats closer to the departure date on undersold flights."
I certainly hope so!
I have a flight from LHR to SIN next month in PE (BA11) and have been checking literally daily for any new reward seats considering it will cost no more points (just taxes and a points change fee) if there are any new business reward seats.
My current 318k OWA itinerary includes the above flight, and has been re-calculated to 318k due to all other flights being in business, hence the keen-ness of getting a business reward seat if available.
I'm not a fan of the 2-4-2 and 2-3-2 business class layout, but it should be better than PE - also considering there are no more 2 x side-by-side seats on the side sections (ie. someone has taken the window seat, either by paying BAs ridiculous seat selection fee (AUD$120+!) or some other method).
This means both my partner and I will now have to sit next to another random passenger which was of course wanted to avoid, but wasn't willing to pony up another AUD$250 just to select seats.
At the moment there's not even any economy reward seats available on the day I need.
I've also been checking seats.aero daily too, all without success.
Here's to hoping BA release some more award seats in the next few weeks. I can then finally have a full business OWA!
