Booked two flights with Jetstar from Sunny Coast to Sydney then Sydney back to Phuket months ago, unaware at the time I would need some extra luggage. I have just today gone online to purchase an extra 3kg carry on only to come to the realisation it costs an extra $50!! Oh, I'm sorry, $49 as the online chat representative advised me; or $61 to check in up to 15kg - a great 2% discount from check-in costs. I remember the days carry on was up to 10kg and you could also check in your bags up to 10kg for no cost. Looks like I'll be wearing 3kg extra clothing to avoid your scam.
