Anyone else found that the prices for these are going up even allowing for the USD/GBP changing from earlier in the year

Yes - In fact the YUP fares are becoming an endangered species. Fares on key routes (such as Las Vegas, Orlando connecting with major hubs) have recently doubled in cost. Typically, DFW to LAS was around £230 back in March, over the summer and currently, the same trip will set you back £550 for the same YUP fare basis.
There are still some out there, its just a question of trying things out.
Personally, I find AA.com the easiest and cheapest to do this as they don't charge the £5 booking fee that Expedia charge. You need to choose First with restrictions on AA.com.
