Ok, after considerable discussion about oneworld's changes to through checking, it may be useful to have a record of who is and isn't allowing through checking.
The basic premise of the thread is to discuss airlines that will through check or tag baggage* to an ultimate destination that is on a different itinerary (PNR) to the first flight being checked in for.
* Using the term "through check" baggage, although in some circumstances, baggage may be tagged to final destination, but require collection and redeposit, usually due to immigration and customs regulations, such as journeys SYD-LAX-JFK or SIN-SYD-CBR.
Also note that is always the policies of the first airline (airline being checked in with) coupled with the agreements it has with other airlines that will dictate what happens in each situation. Just because SQ allows through checking to NZ on separate PNR's doesn't mean that NZ will allow through check to SQ and vice versa.
Qantas
Have indicated they will through check only on separate PNR's in the following situations:
QF->QF
QF->EK
Suggestion also that they will through check QF->oneworld where going from an award to a commercial booking or vice versa.
Air New Zealand
Will NOT through check on separate PNR's, even NZ->NZ
American Airlines
Will NOT through check on separate PNR's, even AA->AA
British Airways
Will NOT through check on separate PNR's, even BA->BA
Singapore Airlines
Policy currently is to through to check to carriers they have agreement with. This includes most "traditional" carriers, but excludes low cost carriers such as Jetstar, Tiger, Air Asia, Cebu Pacific.
