LX First / NZ business versus BA First
Myself and my partner are going to the US in the summer on a redemption and while I was able to book SQ going out, I was not able to get anything remotely decent through DC for the return leg.
I have therefore booked 2 seats on F with BA coming back from SFO to LHR, for a total of 150,000 avios and £600 odd.
However I still have about 50,000 DC miles, so should two seats in Air New Zealand C or Swiss F come up, would I be stupid not to book those instead?
Assuming any unused DC miles are going to get converted to Avios at 1:1, this means my DC miles will get converted to 50,000 avios. Therefore in the long run I would save 100,000 avios by cancelling my BA booking and booking with Swiss or Air New Zealand.
I guess my question is, is BA F worth paying 3 times the miles for over the alternatives or would I be completely dumb not to try and book an alternative and save 2/3rds of my miles.
