I redeemed 26th, and yesterday the mis grupon section showed my voucher moved from disponible to canjeado (AVAILABLE to REDEEMED), and today I received an email asking me about my experiences using groupon with Iberia. took immense willpower to not send back a 1-star feedback thanks to my lack of confidence in Spanish. But now I think it just means I am 3 days away from actually getting the miles... I HOPE.
