I went to Adelaide from Perth . Perth airport Jetstar customer service measured my baggage and got positive sign for carry on 3 baggages. We have family of 3 person including my 4 years one. We always need to take her little bag with full of necessary things like water and wipes and an extra dress. That’s it. My wife has a Vanity bag. So the Perth airport Jetstar allowed us to go. Nice. Now at Adelaide during returning, they asked me you need to weight all the bags including my daughter’s small bag and my wife’s vanity bag and they said it should be total 21 kg for all the carry on baggages. Now I told them several time that Perth airport didn’t even measure those small bag how come you measuring those? They said what happened in Perth stays in Perth this is Adelaide. you are very lucky in this case that Perth didn’t measure it. I said are you the same airline people or just the normal random public providing service here. They said niye you need to cal down and pay $60 for the extra weight which is like 2 kg from my daughter ‘S small bag and my wife’s vanity bag . Otherwise they wouldn’t allow us to go. WTH and WTF. I was furious and said ok take my money and this is the last time ever in my life to board on Jetstar at Adelaide.
