I'm a 1K MM on UA, but live in Dublin. I do the DUB-LCY trip on BA a bunch, and travel back to the US 5-6x/year for business, another 1-2x on my own dime. I also have some travel to APAC, which I've been doing on LH/SQ. I tend to hop in LHR/FRA to get to the US so I can upgrade vs flying DUB-EWR and then onward.

I'm seriously considering matching over to EXP on AA, where I could take better advantage of my regional flying, and eventually get my Aer Lingus flying into a meaningful program once they rejoin OW. Being a *A flyer over here is not easy.
