Let's fly, let's fly away...

So, I'm going to Adelaide soon for a friends 21st birthday! The planning is going terribly because it's right at the end of exams and thus, I have no idea at this stage when exams are. While stating how clueless I was to anything concerning the end of the year, the friend I am (hopefully) traveling with announces "you only need carry on luggage, righ!" No! Then we got into this big debate about what is considered carry-on luggage.

The website says...

"Passengers travelling on (Name of company here):

Cabin Baggage limits are strictly applied. Each Passenger (except infants not occupying an aircraft seat) is permitted 1 main item of Cabin Baggage and 1 other small item, with a total combined weight of up to 10kg (JQ) or 7kg (BL). If you are travelling with an infant, you may also carry on infant food for consumption inflight. If a seat has been booked for an infant, an approved infant car seat is permitted.

Each Passenger travelling on a StarClass fare is permitted 1 additional main item of Cabin Baggage provided that only one item may be a suit pack or garment bag, provided that each main item does not exceed 10kg, with a total combined Cabin Baggage weight of up to 20kg.

* Dimensions of main items must not exceed 56cm (width) 36cm (height) 23cm (depth) for an overnight bag, laptop bag or briefcase, or 11cm (height), 60cm (width) and 114cm (length) for a suit pack or garment bag (measured unfolded).
* Small item may be a small handbag, pocket book or purse, coat, umbrella, or for international flights, duty free goods (where permitted)
* Each piece must be able to fit under the seat in front of you or fit in an enclosed storage compartment in the cabin of the aircraft
* If any piece of Baggage does not comply with any of these conditions, it must be checked in to the aircraft hold or may not be carried on your flight"

And thus the bet is on. 5 days with only carry-on luggage. For her, not me.
I am prepared to lose this bet but goodness isn't it fun.

Rules: Shopping is permitted but every item must be interchangeable with one brought from home. And I plan on being strict with this one, as we know, not all shoes were created equal. Though I'm going to lose on this technicality because she's traveling internationally so can go nuts with the shopping and put it in her big bag. She doesn't have to take it home in the same way. Oh well.
