point differences
Just a query, I'm flying to Perth this summer and have noticed there are some differences in the points earned with diamond club for the same LHR-PER flight, for example
Lauda (170+15)=185
New Zealand (150+150+30)=330
Thai (170+170)=340
Air Canada (195+195)=390
United=400
Now, does this mean that if I book a flight, for example with NZ but with a UA flight code that I would earn 400 points instead of 330, or do I actually have to fly with UA?
