Due to unforeseen circumstances (care and management of ill relatives) our anticipated start date on a DONE4 ex-IST is slipping once again. Orignially next week, then rescheduled to late January, it now looks like mid-February is the likely start date.

BA in IST have the reservation and say they can issue the tickets and have them ready for us to pick up when we arrive in IST. However, they have the January start date, which now looks doubtful.

I feel like with current exchange rates the sooner we lock in the fare the better. If we pay for the tickets now, does anyone know if there's a limit on how long they can hold them before we get there? From the OWE rules it looks like we can make a date/time change on the first segment without penalty, just not the routing.
