Schedule changes?
 

In early November I have a TATL itinerary starting on an Iberia domestic leg. In the last three months Iberia has changed its schedule twice. No notice of schedule change or rebooking was ever received.
Is it likely that Iberia will make another change in their domestic schedule again, or should I call to rebook now?

Impossible to say because it is likely that even IB knows at this point. I would adjust the booking as is convenient for you today and then be prepared to do so again should it change.

TATL isn't likely to happen in November. Might as well wait for the cancellation and insist upon your refund...

So is IB flying TATL as well or a different carrier?

Changed IB domestic flight to what’s presently in the schedule for November. My TATL flight is on AA.

Is your ticket issued by IB or AA?

Even if you could change without fee, there is no guarantee schedule of new flight won’t change.

Ticket issued by AA. Hopefully IB won’t change their domestic schedule a third time!
