I am working to book an August itinerary for son and SO.
They have vouchers from previously cancelled (during COVID). iberia itinerary. (~1250$)
The expiration of these is 1/30/2023 for booking, and 7/31/2023 for travel. I am ready to book today.

Some questions.
1. Any experience share with getting iberia to allow voucher application or extending travel date on a voucher like this? (would like to book 2 one way flights on 8/13 which will consume full voucher amount (BCN->BOS). The flight is iberia operated.

2. I am a AA EXP, and have attempted to get EXP desk to help, but all they can do is transfer me to OneWorld Emerald Desk at Iberia (Which is only spanish speaking).

3. Can someone share privately a phone number to get to an english speaking Oneworld Emerald Desk at Iberia?

Calls to iberia US Customer service have yielded a number of different reactions
1. No chance, the expiration is the expiration
2. Some subtle mention of a voucher department (anyone have experience share about this or how to get to them?

thanks in advance for any experience/share. guidance.

my next shot is to try to reach the voucher department on monday
