Any Dp's re: cancelled Amex for Delta lounge at LGA.
As a side question-- on what does it depends whether or not the agents allow access into the lounge with a cancelled Amex? I mean, if they have a way to confirm the validity of the card, then I imagine that they all would. Or is it just that some agents are too lazy to swipe and check? Seems unlikely considering how strict they are with everything else.
