Sorry for the confusion. AUH-LHR w/ train to W-S-M was our initial go-to itinerary, but EY does not have availability in economy for 9/16. I was just trying to find alts from AUH to BRS, and AMS seemed to be the closest airport to BRS. Still new to this. haha We have friends near LHR, so we were going to visit them too, but Dismaland is one of those "once in a lifetime" events, so it would be great to go there even just for that. We plan to stay until the 18th or 19th. Hope I've cleared this up.

We prefer award. We fly coach most of the time. I've already checked AUH-LHR flights and the cheapest, Royal Jordanian, is going for $398 pax ow. So, award flights has to be the go-to. We are only looking for 2 OW flights as we will head over to MUC (which was our original plan) from LHR.

We have:
AA - 105k
DL - 35k
BA - 11k
UR - 110k (would rather save these for Hyatt stays)
MR - 205k

Thoughts? Let me know if I still need to elaborate. I would like to know how to do this too, so I know for the next time.
