This is a budget airline. There are no extras unless you pay for them. A word of warning though, they do weigh your carry on luggage at some airports (Brisbane is one of them) and if you are over the luggage limit they will ask you to pay for it. You need to think about if the extras are worth paying for or going with say Qantas which has baggage included but cost extra to fly. The seats are very small so if you are a tall man you will need the emergency row. Flights like all airlines can be delayed but you will get to your destination eventually, just don't take it out on ground staff to much as it's nothing they can control. They do have assistance for disability or elderly travelers you have to ask for and preferably in advance.
