Hello:
I often book as far in advance as allowed and have this challenge every time.
What they typically do is:
- book/ confirm you on a factious trip from Australia to Canada on a day that is in the system. i.e before the day you want to go to Australia.
- book you on a return to Australia on the day you wish to go to Australia. ( trips is booked in reverse)
- You call back when the return date is in the system. They then cancel your fictions trip from Australia and and make the corrections.
You are not charged for a call where they just answer questions. Your are charged if you make a booking.
A note is made in the file that you can make 1 change without a charge. When you fix the booking you are not charged again.
There is a risk. You are not guaranteed available space on the day you want to return. Space is given 1st come, 1st serve. I suggest you get up early and phone as soon as the center is open for both the outbound and return. If you never get what you want after the original booking, i.e. can't get the correct return portion, you would have to pay the cancellation fee.
If you get up early and it is not available. Have some flexibility try again the next day. also, remember others also have bookings they don't want and cancel later. Space may clear so keep trying. So far, I have eventually got what I want. I have 6 people going to Florida in prime time by following this approach. Mom and dad are in J and the other 4 in the back!
In essence you are booking your intended trip in reverse and fixing it later.
Good luck
