e.g. SYD-HND - you could fly JAL or QF on that route, but JAL are more generous.
Sadly with the latest changes as of 3 hours ago, it looks like BA isn't the best one to credit these flights to. The base fare plus fuel surcharge in GBP is equal to the TP you'll receive, but it's not clear which airlines BA will get fare information from. Presumably only from AA, IB and BA flight codes. The rest have variable %s on distance travelled, which makes this a nightmare to calculate!
