Hi there. My credit card has recently offered me a choice of a year at any of Delta, AA, and "Lounge Club" airport lounges.

I am a UA / Lufthansa flier.

I spend lots of time at the following airports:

LHR (Europe flights, some US-UK)
LGW (Europe flights, some US-UK)
AMS (UK/AMS)
IAD (US/ UK)
NYC (US, UK, domestic US travel)
GVA (Europe flights only)

(I have included where I travel from/to at these airports in case it makes a big difference.)

Anyone got any recommendations?

Lounge Club at first seemed to be good because it's very international, but Delta seems like they have partners everywhere, too. And Virgin in the UK, which I would imagine would be nice.

Thanks in advance for your input.
