I am moving to TA from NY in July. I am already platinum on Delta and just got comped by ElAl although I have to say that I am appalled by ElAl's platinum - they don't seem to understand customer service. I am gold on AA, at least for now.

Anyway, my business will take me to the US probably twice a month and London maybe once a month - in the US to NYC and SFO primarily. For now I am paying for the tickets myself so super discounted (and ElAl won't upgrade me despite being Platinum) but will likely get arrangements soon where clients will pay for either full fare coach or biz class tickets.

I have a family of four and plan to bring them all to SFO once a year.

So the big question is: should I try to max out ElAl, stick with Delta or maybe try to get comped on Continental now that they are joining the star alliance which gives me Lufthansa, Austrian and CO to the US. Alternatively, I can get comped on AA and then use my AA number when flying ElAl.

Thoughts from the wisdom of this group? This is my first post here so thanks.
