Quick Q - BA have approved an EU261/Expenses claim and said they will pay it. It was authorised and staff.member told me she processed it for payment yesterday but as of now, no sign in my UK bank account (they have correct details).

What is a realistic timescale for payment to clear BA and be recieved - Is it 2-3 working days? I am trying to work out how long to give BA before chasing to ask if they've actually made the payment yet.
