And it is actually probably more than $200 in profit over time and many similar transactions due to breakage (passengers not using the certs) and other factors.
Still doesn't mean they have to do it to be profitable. Unless they are frequently finding themselves sold out on flights they probably are doing pretty well with the current policies. Plus most that factor is likely a positive marketing bullet point, possibly even more significant that the potential incremental revenue it would generate.
