I flew Jetstar in December and being their first flight thought they may be very strict so I took my 'domestic' size wheelie which was within their cabin baggage measurements. My 'international' Qantas brand wheelie was two centimetres too long (even though slightly less in width). There was really no interest in size of cabin baggage, just how much it weighed.
My domestic wheelie is smaller than what I am allowed but I dont want to buy yet another bag so I am wondering if anyone else has taken an 'international' size wheelie on Jetstar and if so, was there a problem? or not? Thank you.
