I'm hoping someone can give me some advice, I'm looking at honeymoon destinations with BA and trying my hardest to save for a couple of flights with miles using Tesco points and the amex card companion voucher.

I'd love to fly LGW-LAX-HNL first class - I see that I'll need 150000 miles for this - does this include the return leg as well?

I'm looking at traveling mid-May 2009, but when I do a dummy booking I cannot see any dates available. Since there's a load of dates in April, I'm assuming May dates will be released shortly?

Does anyone have experience using this route? What's availability like? Should I be booking months in advance? I don't think I'll get my amex companion voucher till November, so will have to book around then.

Thanks for your help
