Here's the nitty gritty.
I have a large chunk of money set aside ~$36K to pay off a student loan.

The company that services the loan seems to only accept ACH payments online.

Any suggestions on making this transaction work for miles somehow?

I currently hold a Citi AA card, Chase BA (100k offer), and Delta Amex. I'm a PhD student so my income is limited and I'd like to find a way to make this work. Maybe one of the banking offers? Thoughts?

Thanks all.
