Can any knowledgeable person explain the bizarre Avios pricing for this booking MAN to BHD this Sunday at 20.15 Booking on BA.com with Emerald Airlines on behalf of Aer Lingus. Taxes and charges off the scale for a one way SH. I assume this is due to a lack of RFS on code share? I'm booking for my niece so I cant transfer to my AerClub account to book.
