I do! And I checked and the value is a bit better than cash, about 15% less, but still doesn’t seem really worth it. I might just pay for 2 seats in the emergency exit, as that will guarantee that neither of us will be sitting next to anyone random. They have a 2 seater aisle. I guess I’m just overall confused why it business class could cost so much more considering it’s almost the same seat as economy, but with an empty middle.
