Always a mixed bag when flying Jetstar.
Often know as LateStar for a very good reason.
Staff on board are friendly, but it isn't the most comfortable airline, so I always pay extra for legroom. They're much more likely to weigh hand luggage too.
Had one booking made and paid for that they swore I never had and had to fight for months to get a refund, or the higher amount from the second booking as they only wanted to refund the lower amount.
Sometimes, travel just shouldn't be this hard.
