Sorry if this is in the wrong forum, I'm sure it will be moved if so.

I haven't flown first class a tremendous amount of times in my life. In the times that I have flown domestic first class, however, I always got lounge access with my ticket. In the last three times I've flown first (all on three different airlines) on domestic routes, I've been denied lounge access because my tickets weren't international first class. Was this a change that all the airlines made recently, or has it been going on for a while? Are there any airlines that still provide lounge access for domestic first class tickets?
