Yes was BA97, LAX will count for 2 of the flights and I will do a quick I class one weekend to get the others, if nothing else happens in the meantime. I'd like to aim to hit the 600 as soon as possible, so I can start earning for Gold.

Thanks to all the rest for your input. Looks like a KUP, LAX-EWR-LAX is in pole position at 650 GBP, bit more expensive than some options, but fairly hassle free. Couldn't find a direct from SNA to the East Coast, only routings through DFW, ORD and the usual suspects, they end up only being 60 TP's a leg.

Thanks again everybody v.useful stuff - hopefully this with YUP in the subject will turn up for others in future searches. ^
