My trip for this week - tried to rebook (AA) with no add/collect. Since my outbound flight has not canceled (SFO/DFW/EZE) AA won't rebook without an add/collect. "I" looks pretty much removed from inventory for months to come. The $2K "I" fare would turn into a nearly $6K "D" fare. No thank you. AA would credit for a full refund, which I took. (She said it will show as a travel credit until it fully processes.... we shall see.)
