We are going to Thailand for 2 weeks in June with DD who will be 26months by then. We did a test flight to Perth last month and I agree that if you can get a seat for your child it will be a lot easier!! On the way over to Perth DD was awake and was good for about 2 hours, before we had to bring out the laptop with the Dora dvd! On the way home we had a midnight flight and she slept the whole way (stretched across the seat so Mummy & Daddy had no sleep at all) but it was so much better having a seat for her.
