I am planning a trip to Las Vegas where my ticket is part expensed so I thought I would take full advantage and try to collect some tier points by spending a bit of my own money on top. No budget or target TP as such (I am currently Blue with ~50TP waiting for a credit) but looking to be relatively efficient.

Parameters:
From EDI to LAS
Depart 29th July - 1st August
Return 10th - 11th August

My current research has given a positioning to Dublin (with Ryanair) and then DUB-LHR-PHL-LAX-LAS-SEA-CLT-DUB 30th July - 11th August for £1,765.

The somewhat hefty layovers on the way home both land in the morning so I could probably find the energy to go on an exploration in lieu of a hotel!

I was wondering if there is any obvious low hanging fruit - perhaps I can return straight to EDI, there is somewhere better to position to, rack up some TPs within Europe instead/as well, or open jaw to somewhere else?
