When you call, have the specific flights numbers in hand.

Redemption space is not relevant, but AA willingness to rebook OA is.

I would ask for the PHL-MAD-DBV and use the AA codeshare flight number with no mention of IB. It's a terrible routing with an 8-hour connection at MAD, but it's better than nothing.

Be prepared to have that cancelled as well.when AA gets around to the July schedule in early June.
