Oneworld is one of the world's largest airline alliances. It's member airlines span the world and offer business travelers a unified means for keeping track of their travels and integrating the travel experience.
While oneworld airlines will manage the transfer of luggage from one member to another, business travelers need to be aware that the baggage policies for oneworld members will differ by airline. Different airlines will have different allowences and weight limits for both carry-on and checked items.
Since the oneworld baggage policies do vary, it's important for business travelers traveling on oneworld partners to verify their baggage policies before heading out. Keep in mind that baggage allowances may also vary by code-share flights and operating carriers.
