Silver: "You can pay to reserve your seats now"
I'm sure I've read something similar on here, but can't remember the answers.
I've just reached BA Silver status, which is showing when I log into my BAEC account. I'm now trying to reserve seats for two existing bookings but am still being asked to pay to reserve seats. I've logged in and out a few times but it still says "You can pay to reserve your seats now" and shows a price for each seat.
I thought I should be able to reserve seats for free. Is there a problem doing this on existing bookings made when I was Bronze?
