After seeing some luggage deals around on OzBargain I went hunting for a <55cm carry-on spinner case and I found this.
Height: 53cm
Width: 36cm
Depth: 23cm + 7cm (expansion zip)
Weight: 2.82kg
Capacity: 47LSingle expander from the middle (25% extra space)
Telescopic handle
Frameless construction
Hard shell
5 year warranty
This fits in within most airline's carry-on restrictions including Qantas, Jetstar, Cathay Pacific and Air New Zealand. Surprisingly not allowed on Virgin Australia as they only allow two small bags (up to 48cm long) or a small bag and a suit-pack.
I bought two of them for some up-coming holidays.
Don't forget to change the currency to GBP and pay using a international-fee free card like 28 Degrees.
isnt this too heavy for carry-on?
