First off, what an amazing resource. I wish I would have found this site sooner. I have a delimma I'm hoping someone can help me with.

I need to book three tickets from RDU to LHR in the next 4-5 days for an Oct. 3-Oct 17 trip. I've been on the British Airways site for the better half of this morning and can't seem to understand how many avios I would have to purchase to get prem economy on an AA flight for this trip.

I know right now, Chase is offering a +30% to transfer points to BA, so I was hoping to do that. Essentially, I would like to buy as much of the flight as I can with avios, although I haven't transferred Chase point yet, because I want to determine the exact amount. Is it possible to book this AA flight with avios only? I can transfer as many Chase points as needed.
