But this is most definitely not the norm - issue I'd guess is that most systems aren't designed to do this - they can take payments, or refund them, but not much inbetween. Perhaps new modern systems have this kind of option, but I wouldn't call most airline systems 'modern' by any stretch. I am on PayPal as a small business as a merchant, and I don't believe there is a way for me to do that, either.
