Then we received emails from the travel agent telling us that there had been schedule changes for our flights, could we please phone to confirm. But when we looked at the new itinerary, we saw that one of the changes had us getting to Chicago at 12.04 am and leaving for Indianapolis at 9.30 pm the day before! It took about a week for them to sort it out with the airline (United). We now have a temporally possible itinerary; we're just hoping they won't change it again!
Here 'tis:
20th December: Depart Indianapolis 5.32 pm (via Chicago and LA)
22nd December: Arrive Sydney
10th January: Depart Sydney 3.15 pm (via LA and Chicago)
Arrive Indianapolis 11.36 pm
So start marking your calendars!
