Hi,

I fly about 8 times per year from London to JFK and then some 5-6 more intra US flights a year. All economy/cheapest possible. Nevertheless, I thought I would be a super-dooper mile club by now (since I managed to get to delta gold a few years ago with many fewer flights), but all programs seems to have devaluated so much that it is hardly worth doing any of that. I'm currently silver on VS and managed two upgrades from economy to upper class in the last 18 months, but that is about it and I also have a virgin CC.
Any ideas which loyalty program should I be using given my pattern? BA seems super stingy with miles. I also can't do EWR since it is oppose where I need to go on long island.

Thanks,
a.
