I booked a 2021 flight for the start date and then dummy dates for each of the flights thereafter about two or three days apart given the flights I want for the end of next year are clearly not available. I discussed with the agent my plan to ring back when the flights I do want become available (somewhere around December this year) and change the dates then. She clearly understood what I was after and actually came up with a couple of flights to fill in a leg of the itinerary I didn't think I would be able to book again.Thank you so much for this. It really gives me hope.
I am going to call and try your method.
Did you already book a new ticket? (if flights have opened up)
Once again, much appreciated.
Let us know how you go!
